A pendulum bob of mass of 80 mg and carrying a charge of 2 X 10-8 C is at rest - Physics - Electric Charges And Fields

Question

A pendulum bob of mass of 80 mg and carrying a charge of 2 X
10- 8 C is at rest in a horizontal uniform
electric field of 20,000 V/m Find the tension in the thread of the
pendulum and the angle it makes with the vertical
Take( g = 9 8ms-2 )

As per the figure

Here m=80mg= $80 \times 10^{- 6} k g$

A pendulum bob of mass of 80 mg and carrying a charge of 2 X 10- 8 C is at rest in a horizontal uniform electric field of 20,000 V/m. Find the tension in the thread of the pendulum and the angle it makes with the vertical. Take( g = 9.8ms-2 )

A pendulum bob of mass of 80 mg and carrying a charge of 2 X 10^- ⁸ C is at rest in a horizontal uniform electric field of 20,000 V/m. Find the tension in the thread of the pendulum and the angle it makes with the vertical.

Take( g = 9.8ms^-2 )
