An insect jumps from ball A onto ball B, which are suspended from inextensible light strings each of length `L=8cm`. The mass of each ball and insect is same. What should be the minimum relative velocity (in `ms^-1`) of jump of insect w.r.t. ball A, if both the balls manage to complete the full circle?

Two indentical pith balls, each carrying charge q, are suspended from a common point by two strings of equal length l. Find the mass of each ball if the angle between the strings is 2theta in equilibrium.

Two identical pith balls, each carrying charge q, are suspended from a common point by two strings of equal length l. Find the mass of each ball if the angle between the strings is 2theta in equilibrium.

A small ball of mass m having charge q is suspended by a string of length L . Another identical ball having the same charge is kept at the point of suspension. Determine the minimum horizontal velocity which should be imparted to ball at lowest point so that it can make complete revolution.

Two small balls, each having equal positive charge Q are suspended by two insulationg strings of equal length l from a hook fixed to a stand. It mass of each ball =m and total angle between the two strings is 60^(@) m, then find the charge on each ball.

Vertical strings of same length L support two balls A and B of mass 2m each. There is a small monkey of mass m sitting on ball A. Suddenly, the monkey jumps off the ball A at an angle theta = 45^(@) to the horizontal and lands exactly on the ball B. Thereafter, the monkey and the ball B just manage to complete the vertical circle. (a) Find distance d between the two string and the speed with which the monkey jumped of the ball A. (b) Find the impulse of the string tension on ball A during the small period when the monkey interacted with the ball to jump off it.
