A ball of mass m=0.5kg is suspended by a thread and a charge q=0.1muC is supplied when a ball with diameter 5cm and a like charge of same magnitude is brought close to the first ball but below it the tension decreases to 1//3 of its intial value .The distance between centres of the balls is

A ball of mass 0.1 kg is suspended by a string. It is displaced through an angle of 60^(@) and left. When the ball passes through the mean position, the tension in the string is

A ball of mass 0.1 kg is suspended by a string 30 cm long. Keeping the string always taut, the ball describes a horizontal circle of radius 15 cm. Find its angular speed and tension.

Two balls of the same radius and weight are suspended on threads so that their surface are in contact. A charge of q_(0) = 4 xx 10^(-7)C is given to the balls which makes them repel each other and diverge to an angle of 60° . Find the mass of the balls if the distance of balls from the point of suspension to the centre of ball is 20cm. Find the density of the material of the balls if the angle of divergence becomes 54° when the balls are immersed in kerosene of density 800kg m^(-3) dielectric constant ofkerosene is epsilon_(r) = 2 [1.592g, 255 K//g m^(3)]

A ball of mass 0.5 kg slows down from a speed of 5ms^-1 to 3ms^-1 , calculate the change in the kinetic energy of the ball.

A charged ball of mass 5.88xx10^(-4) kg is suspended from two silk strings of equal lengths so that the strings are inclined at 60^(@) with each other. Another ball carrying a charge which is equal in magnitude but opposite in sign of the first one is placed vertically below the first one at a distance of 4.2xx10^(-2) m . Due to this, the tension in the strings is doubled. Determine the charge on the ball and the tension in the strings after electrostatic interaction. (g=9.8 m//s^(2))
