A small plastic ball is connected to a lightweight cord of length L-1.40 m that is tied to a point P, as shown in the figure.

The ball string and point all lie on a frictionless, horizontal table. The ball has a mass m = 0.0100kg, a charge q = +2.10 C and is released from rest when the string makes an arigle θ = 60.0° with a uniform
electric field of magnitude E= 350 V/m. Determine the speed (in m/s) of the ball when the string is parallel to the electric fleld.
Concept: here we use work energy theorem to
find the final speed of the particle in the electric field. Work is
done by the force of the electric field,

ill be sure to rate
My Notes 4. -/1 points SERPSE 10 24.1.OP.005.MI. An electron moving parallel to the x axis has an initial speed of 4.14 x 10 m/s at the origin. Its speed is reduced to 1.50 x 10 m/s at the point x = 2.00 cm. (a) Calculate the electric...
A small m=1.81E-3kg plastic ball is suspended by a l=20.0cm long string in a uniform electric field, as shown below. If the ball is in equilibrium when the string makes a θ=12.8deg angle with the vertical, what is the net charge on the ball? Take E=1.84E+3iN/C.
A small 1.45 g plastic ball that has a charge q of 1.75 C is suspended by a string that has a length L of 1.00 m in a uniform electric field, as shown in the figure. If the ball is in equilibrium when the string makes a 9.80 angle with the vertical as indicated by θ, what is the electric field strength E?
A small 12.6 g plastic ball is tied to a very light 28.6 cm string that is attached to vertical wall of room (see figure). A uniform horizontal electric field exists in this room. When the ball has been given an excess charge of - 1.33 μC, you observe that it remains suspended, with the string making an angle of 17.4° with the wall. Find the magnitude of the electric field 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.

Problem 5: A cord with length L 2 m has a ball of mass m 1 kg attached to the end. The ball is released from rest, when the cord makes an angle of 30° with the vertical. 1) How much work does the gravitational force do on the ball from A to B? 2) What is the speed of the ball at point B? 3) What is the tension in the cord at point B? 4) What initial velocity...
