A "0.50gm" ball carries a charge of magnitude 10 `mu` C" It is suspended by a string in a downward electric field of intensity "300N/C" .If the charge on the ball is positive,then the tension in the string is `g=10ms^(-2)`

A sphere of mass "50gm" is suspended by a string in an electric field of intensity 5NC^(1) acting vertically upward.If the tension in the string is "520 millinewton,the charge on the sphere is "( g=10ms^(-2)) ]

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 mass m carrying a charge q si suspended form a string and placed in a uniform horizontal electric field of intensity E .The angel made by the string with the vertical in the equilibrium position is

A small sphere of mass 1g carries a charge of + 6 muC . The sphere is suspended by a string in an electric field of 400 NC^(-1) acting downwards. Calculate tension in the string. What will be the tension if charge on the sphere were -6 muC ?

A bob of pendulum of mass 50 g is suspended by string with the roof of an elevator. If the lift is flying with a uniform acceleration of 5m s^(-2) the tension in the string is (g = 10m s^(-2))

A mass of 10 gm is suspended by a string and the entire system is falling with a uniform acceleration of . 400cm//sec^(2) The tension in the string will be (g=980cm//sec^(2))

A simple pendulum is oscillating with an angular amplitude 60^@ . If mass of bob is 50 gram, then the tension in the string at mean position is (g = 10 ms^(-2))
