A ball of mass 0.25 kg is suspended by two strings as shown in the diagram below. (a) Determine the weight of the ball, in N, (b) Determine the magnitude of the tension T1, in N, (c) Determine the magnitude of the tension T2, in N, Use g=10m/s/s, and round your answers to the riearest tenth. Do not include units in your answers, Use the following trigonometric values as needed: sin 37-0.6; cos 37-0.8 an sin 53-0.8: cos 53=0.6
5. Two identical conducting spheres hang from a light-weight string carry 10 nC of charges each maintain equilibrium state at a distance of 5 mm from each other while making 0-10o from the vertical line. Find the weight of the spheres.
Two identical spheres with mass m = 3.6 × 10-6 kg are hung from silk threads of length L = 0.8 m, as shown in the figure. Each sphere has the same charge, so q1 = q2 = q = 1 nC. The radius of each sphere is very small compared to the distance between the spheres, so they may be treated as point charges. With the approximation of small angles (θ is small so tan theta approximately equal to...
Two identical small metal spheres withqi > 0 and attract each other with a force of magnitude 81 mN when separated by a distance of 2.65 m. r2 27 m 21 F12 1 42 2.65 m The spheres are then brought together until they are touching, enabling the spheres to attain the same final charge q. 29 After the charges on the spheres have come to equilibrium, they spheres are separated so that they are again 2.65 m apart. F21...

An object with weight W is dragged along a horizontal plane by a force acting along a rope attached to the object. If the rape makes an angle with the plane, then the magnitude of the force is F= u sin() + cos(8) where u is a constant called the coefficient of friction. (a) Find the rate of change of F with respect to(0). - W( cos A-sin) (usin 0 + cos 0) df de- (b) When is this...
CL-3. Two identical conducting spheres are held on insulating stands with their centers 0 shown below. Sphere A Sphere B 0.300m While in this position each sphere repels the other with a force of 1.60N. The two spheres are brought into contact with each other and allowed to reach electrostatic equilibrium (for which they have equal final charges). The spheres are then returned to their original separation where they are now found to repel each other with a force of...
9) Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of magnitude F due to the other. With time, the charge of each sphere gradually diminishes. When each of the spheres has charge equal to half its initial magnitude, what will be the magnitude of the electrostatic force on each one? A) 1/16 F B) 1/8 F C) 1/4 F D) 1/2 F
QUESTION 8 Two identical spheres with mass m = 3.1 × 10-6 kg are hung from silk threads of length L = 1 m, as shown in the figure. Each sphere has the same charge, so q1 = q2 = q = 2.2 nC. The radius of each sphere is very small compared to the distance between the spheres, so they may be treated as point charges. With the approximation of small angles (θ is small so tan theta approximately...

Sample Class Problems-Force and Acceleration Prob#l: Two people are pushing a stalled car (the mass of the car is 1850kg). One person applies a force to the car, while the other applies a force of 395N. Both forces act in the same of 560N also acts on the car, but in a direction opposite force arises because of friction and the extent to which the pavement opposes Find the acceleration of the car. direction.
