Small identical balls with equal charges are fixed at vertices of regular 2009 -gon with side a. At a certain instant, one of the balls is released & a sufficiently long time interval later, the ball adjacent to the first released ball is freed. The kinetic energies of the relased balls are found to differ by K at a sufficiently long distance from the polygon. Determine the charge q of each part.

Small identical balls with equal charges of magnitude 'q' each are fixed at the vertices of a regular 20019-gon (a polygon of 2019 sides) with side 'a'=4 . At a certain instant, one of the balls is released and a sufficiently long time interval later, the ball adjacent to the first released ball is freed. The kinetic energies of the released balls are found to differ by K=9xx10^(9) J at a sufficiently large distance from the polygon. determine the charge q in mC.

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.

The balls are released from the top of a tower of heigh H at regular interval of time. When first ball reaches at the grund, the nthe ball is to be just released and ((n+1))/(2) th ball is at some distance h from top of the tower. Find the value of h .
