A small plasticl ball is tied to a very light 26.0 cm string that is attached to the vertical wall of a room. A uniform horizontal electric field of magnitude 36,000 N/C exists in this room. When the ball has been given an excess charge Q = -1.10 uC, you observe that the ball remains suspended, with the string making an angle of 17.4 degrees with the wall. A) What is the direction the electic field E in the room?...
A small 12.6 g plastic ball is tied to a very light 28.4 cm string that is attached to the vertical wall of a room. (See the figure (Figure 1).) A uniform horizontal electric field exists in this room. When the ball has been given an excess charge of -1.10μC , you observe that it remains suspended, with the string making an angle of 17.4° with the wall. Part A Find the magnitude of the electric field in the room. Part B Find the...
In an electricity experiment, a 1.10 g plastic ball is suspended on a 60.0 cm long string and given an electric charge. A charged rod brought near the ball exerts a horizontal electrical force F⃗ elec on it, causing the ball to swing out to a 23.0 ∘ angle and remain there. What is the tension in the string?
In an electricity experiment, a 1.20 g plastic ball is suspended on a 58.0 cm long string and given an electric charge. A charged rod brought near the ball exerts a horizontal electrical force F⃗ elec on it, causing the ball to swing out to a 23.0 ∘ angle and remain there. Part A What is the magnitude of F⃗ elec? Part B What is the tension in the string?
A small sphere of charge q+67 pC and mass m-5.4 g is attached to a light string and placed in a uniform electric field e that makes an angle θ-31° with the horizontal. The opposite end of the string is attached to a wall and the sphere is in static equilibrium when the string is horizontal as in the figure shown below. (a) Construct a free body diagram for the sphere. (Submit a file with a maximum size of 1...
A 6.70-g charged insulating ball hangs on a 26.0 cm long string in a uniform horizontal electric field, as shown in the figure below. Given the charge on the ball is 8.20 μC find the strength of the neldN/C 8°
A uniform meter stick of mass 1.5kg is attached to the wall by a frictionless hinge at one end. On the opposite end it is supported by a vertical massless string such that the stick makes an angle of 40 degrees with the horizontal. Find the tension in the string and the magnitude and direction of the force exerted on the stick by the hinge.

A bob of mass 0.320 kg is attached to one end of a light inextensible string of length 0.600 m, whose other end is attached to a fixed pivot. The bob performs uniform circular motion in a horizontal plane, with the string making an angle of 30.0° with the vertical. What is the angular speed of this circular motion? Give your answer in raduans. (Hint: you can begin by using Newton's second law in the vertical direction to find the...
2. (50 points) A uniform rod of length L and mass m is hinged to a wall at one end and suspended from the wall by a cable that is attached to the other end of the rod at an angle of B to the rod (see figure below). Assume the cable has zero mass. There is a contact force at the pivot on the rod. The magnitude and direction of this force is unknown. In this problem you will...
