A pendulum bob of mass 80mg and carrying a charge of 2*10-8C is at rest in a horizontal uniform electric field of 2*104 V/m. Find the tension in the thread of the pendulum and the angle it makes with the vertical.
Answers
Answer:
A particle starts from rest and moves along z-axis. The acceleration a varies [yith its displacement x as a = (2 - x) m/s. Find magnitude of acceleration of particle when its displacement along positive x axis is maximum.K-Kerosene, S-Coloured saline water, W- pure water.
