A pendulum bob of mass m charge q is at rest with its string making an angle `theta` with the vertical in a uniform horizontal electric field E. The tension in the string in

A small ball of masss m and charge +q tied with a string of length l, rotating in a veticle circle under gravity and a uniform horizontal electric field E as shown. The tension in the string will be minimum for

A pendulum bob of mass 80mg and carrying a charge of 2xx 10^(-8)C is at rest in a uniform, horizontal electric field of 20k Vm^-1. Find the tension in the thread.

A pendulum bob of mass 80mg and carrying a charge of 2 times10^(-4) coulomb is at rest in a uniform horizontal electric field of 20kV/m .The tension in the thread of the pendulum is x times 10^(-4) N.Find value of x?

A pendulum bob of mass m and length L is released from angle theta with the vertical. Find (a) the speed of the bob at the bottom of the swing and (b) tension in the string at that time

The block of mass m is at rest. Find the tension in the string A .

A pendulum bob of mass m = 80 mg, carrying a charge of q=2xx10^(-8)C , is at rest in a horizontal, uniform electric field of E = 20,000 V/m. The tension T in the thread of the pendulum and the angle alpha it makes with vertical, is (take g=9.8m//s^(2) )

A simple pendulum is constructed by attaching a bob of mas m to a string of length L fixed at its upper end. The bob oscillates in a vertical circle. It is found that the speed of the bob is v when the string makes an angle theta with the vertical. Find the tension in the string at this instant.

A body of mass mis suspended by two strings making angles alpha and beta with the horizontal. Find the tensions in the strings.

A 1N pendulum bob is held at an angle theta from the vertical by a 2N horizontal force F as shown in figure. The The tension in the string supporting the pendulum bob (in newton) is .
