Class 12 Physics Electrostats Electric Potential

Small identical balls with equal charges are fixed at the vertices of a regular polygon of N sides, each of length d. At a certain instant, one of the ball is released. After long time interval, the adjacent ball to the previous one is released. The difference in kinetic energies of the two released balls is K at a sufficiently long distance from the polygon.

(a)

Final kinetic energy of the first ball is greater than that of the second ball

(b)

Final kinetic energy of the second ball is greater thn that of the first ball

(c)

Charge on each ball is $2πϵ_{0}dK $

(d)

Charge on each ball is $4πϵ_{0}dK $

Correct answer: (a) (d)
