Question

5: Three charges of equal mass are arranged as shown. They are suddenly released from rest. Describe and explain the subsequent motion of each charge. Make sure you describe what happens to their velocities and accelerations as time passes. 6: Three charges are held in place as shown. Find the magnitude and direction of the net electric force on Q. UseQ2nC. SM -3Q 3 M 7: A: The three charges in the diagram are initially held stationary. If the charge at the origin is released from rest, what quadrant will it move into (I, II, Ill or IV)? Explain 111-29

Answer 1

5) All the charges of same nature, repels each other, Left charge moves towards left and right side charge move towards right, and the charge in middle remains at rest because net force on middle charge is zero due to other two charges.

Velocity and acceleration of both the left and right charges decrease with time because their distances increase with time from other charges, and net force decreases on them.
