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 0.50 gm ball carries a charge of magnitude 10mu 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 = 10 ms^(-2))

Two strings are attached to two nails in the same horizontal level and knoted at a point . A mass of 2 kg is suspended from the knot . If the strings make angles of 30^(@) and 60^(@) respectively with the vertical the tensions in the strings are

Simple pendulum of mass 3 Kg is pulled aside through an angle of 60^(@) to the vertical. Calculate the horizontal force and tension in the string.

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 block of mass 0.2 kg is suspended from the ceiling by a light string. A second block of mass 0.3 kg is suspended from the first block through another string. Find the tensions in the two strings. Take g=10 m/s^2 .
