Answer 1

Question

The bob of a pendulum is positively charged another identical charges placed at the point of the suspension of the pendulum the the time period of the pendulum becomes

Solution

➠ A charge is placed on a bob and a charge is placed at the suspension point of the pendulum

➠ The electrostatic force is compensated by increase in tension of the string. Both the forces act along the same line,thus they wouldn't cause any elongation in the length of the pendulum.

➠ Since,there is no visible change in the length of the pendulum. The time period isn't subjected to change

The time period remains the same

$\sf{reamains \: the \: same}$

●The force due to the charge kept at the suspension point always acts along the wire which is compensated by increase in tension of the string.

☆A charge is placed on a bob and a charge is placed at the suspension point of the pendulum

________________________

●This force never accounts for change in time period since it has no component perpendicular to the wire.

☆The time period isn't subjected to change

so it reamains the same
