Two particles have equal masses of 5.0 g each and opposite charges of +4.0 xx10^(-5) C. They are released from rest with a separation of 1.0 m between them. Find the speeds of the particles when the separation is reducced to 50 cm.

Two charged particles having charges 1 and -1 mu C and of mass 50 g each are held at rest while their separation is 2 m . Now the charges are released. Find the speed of the particles when their separation is 1 m .

Two charged particles, having equal charges of 2.0xx 10^(-5) C each, are brought from infinity to within a separation of 10 cm. Find the increase in the electric potential energy during the process.

A particle of mass 2 g and charge 1 muC is held at rest on a frictionless surface at a distance of 1m from a fixed charge of 1 mC. If the particle is released it will be repelled. The speed of the particle when it is at distance of 10 m from fixed charge is :

Two identical charges, 5 muC each are fixed at a distance 8 cm and a charged particle of mass 9 xx 10^(-6) kg and charge -10 muC is placed at a distance 5 cm from each of them and is released. Find the speed of the particle when it is nearest to the two charges.

Electric field E = – bx + a exists in a region parallel to the X direction (a and b are positive constants). A charge particle having charge q and mass m is released from the origin X = 0. Find the acceleration of the particle at the instant its speed becomes zero for the first time after release.
