A small glass bead has been charged to ++ 30 nCnC . A tiny ball bearing 2.0 cmcm above the bead feels a 1.8×10−2 NN downward electric force. What is the charge on the ball bearing

The visible portion of a lightning is preceded by an invisible stage in which a column of electrons moves from a cloud to the ground. The linear charge density λ along the column is typically -1 x 10-3 C/m. If air molecules are ionized in an electric field exceeding 3 x 106 N/C, what is the radius of the column?

Two large metal plates of area 1.0 m2 face each other. They are 5.0 cm apart and have equal butopposite charges on their inner surfaces. If the magnitude of the electric field between the plates isE 55 N C, what is the magnitude of the charge on each plate?

For this physics II problem its saids a 4.00 g ping pong ball is suspended from a light thread and given an electric charge. The ball is then placed in a uniform electrci field of magnitude 110,00N/C which causes the ball to swing out to an angle of 23 degrees. What is the sign and magnitude of the charge on the ball? The ball is angled to the right.    If you can break this down into step that would be great. Thanks!

In the figure above, charge A is -4.85 nC, charge B is 9.70 nC, and charge C is 4.85 nC. If x = 4.30 cm and y = 8.60 cm, what is the electric field at the dot? 3.03×104 N/C, 19.4o counter-clockwise from the positive x-axis 2.28×104 N/C, 38.9o clockwise from the positive x-axis 3.03×104 N/C, 38.9o clockwise from the positive x-axis 2.28×104 N/C, 19.4o clockwise from the positive x-axis

A 148 mg plastic bead has a radius of 344 μm and is charged by the addition of 1.38×1010 excess electrons. You may assume that the excess electrons are spread uniformly throughout the bead. What electric field strength will cause the bead to hang suspended in the air?

Two particles having charges q1 = 0.500 nC and q2 = 8.00 nC. The first charge is located at x=0, y = 3 cm and the second charge is located at x = 5 cm, y = 0. What is the magnitude and direction of the electric field at the origin (x = 0, y = 0)?

What should be the direction and magnitude of the vertical electric field that will balance the weight of a plastic sphere with the charge Q= +1.5 nC and mass m= 1.8 g? 3.2 x 10^5 N/C positive y-direction 1.2 x 10^6 N/C in +y-direction 1.2 x 10^6 N/C in negative y-direction 3.2 x 10^5 N/C in negative y-direction

Charge Q acts as a point charge to create an electric field . Its strength measured from a distance of 30.0 cm away is 40.0 N/C. What is the magnitude of the electric field strength that you would expect to be measured at a distance of 45.0 cm away?
