As in the figure, a uniform sphere of mass = 0.84 kg and radius r = 4.2 cm is supported by a string (of negligible mass) attached to a wall (whose friction can also be ignored). The center of the sphere is a vertical distance L = 10 cm below the attachment point of the string. Find the tension in the string. (Note that the direction of the tension (along the string) is along a line passing through the center...
Question 2 1 pts As in the figure, a uniform sphere of mass = 0.82 kg and radius r = 5 cm is supported by a string (of negligible mass) attached to a wall (whose friction can also be ignored). The center of the sphere is a vertical distance L = 8.5 cm below the attachment point of the string. Find the force on the sphere from the wall. Your answer should be in N, but enter only the numerical...
As in the figure, a uniform sphere of mass = 0.8 kg and radius r = 4.2 cm is supported by a string (of negligible mass) attached to a wall (whose friction can also be ignored). The center of the sphere is a vertical distance L = 9.5 cm below the attachment point of the string. Find the force on the sphere from the wall. Your answer should be in N, but enter only the numerical part in the box.
In the figure, a uniform sphere of mass m=12 kg and radius r= 4.2 cm is held in place by a massless rope attached to a frictionless wall a distance L= 45 cm above the center of the sphere. Find the pushing force on the sphere from the wall. L Select one:
In the system shown below, there is a block of mass M = 3.6 kg resting on a horizontal ledge. The coefficient of kinetic friction between the ledge and the block is 0.25. The block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging block of mass m = 2.2 kg. The pulley is a uniform disk of radius 7.9 cm and mass 0.66 kg. Find the...
Two objects are moving in the xy-plane. Object A has a mass of 3.2 kg and has a velocity vA = < 2.3 m/s, 4.2 m/s > and object B has a mass of 2.9 kg and has a velocity vB = < -1.8 m/s, 2.7 m/s > . What is the total momentum of the system? A uniform sphere of radius 2R has a spherical cavity of radius R cut out of it. The center of the cavity is...
Question 1 2 pts The figure shows a climber of mass 68 kg held up by a rope connected to her climbing harness. The force of the rope has a line of action passing through her center of mass. The angle = 45 degrees and o = 28.9 degrees. If her feet are just about to slide on the vertical wall (i.e., the friction is at its maximum), what is the coefficient of static friction between her shoes and the...
The sphere of mass M and radius R is rigidly attached to a thin rod of radius r that passes through the sphere at distance ½R from the center. A string wrapped around the rod pulls with tension T. (Figure 1) Part A Find an expression for the sphere's angular acceleration. The rod's moment of Inertia is negligible
2. A small box of mass m is kept on a fixed, smooth sphere of radius R at a position where the radius through the box makes an angle of 30° with the vertical. The box is released from the position. (a) What is the force exerted by the sphere on the box just after the release? (b) Find the distance travelled by the box before it leaves contact with the sphere. 3. A particle is suspended from a fixed...
A)A sphere of radius 4.11 cm and uniform surface charge density +11.0 μC/m2 exerts an electrostatic force of magnitude 4.21×10−2 N on a point charge +1.40 μC . Find the separation between the point charge and the center of the sphere. B)The electric field between the plates of a parallel-plate capacitor is horizontal, uniform, and has a magnitude E. Asmall object with a charge of -2.13 μC is attached to the string. The tension in the string is 0.440 N...
