The bob of a simple pendulum is positively charged. A negatively charged metal plate is placed just below the bob as the pendulum starts oscillating. How will it affect the time period of the pendulum?

A bob of a simple pendulum of length l is negatively charged. A positively-charged metal plate is placed just below the bobt and the pendulum is made to oscillate. What will be the effect on the time period of the pendulum?

The bob of a perpendicular is positively charged.Another identical charge is placed at the point of suspension of the pendulum.The time period of pendulum

A bob of pendulum was filled with Hg and entire Hg is drained out, then the time period of pendulum

If the time taken by a simple pendulum to com-plete 16 oscillations is 4 seconds, what is the time period of the simple pendulum ?

The metal bob of a simple pendulum is positively charged and has certain time period in air. If bob oscillates above a negatively charged metal plate. Its time period now

Suppose the bob of a simple pendulum is made up of ice. What will happen to the time period if the ice starts melting?

If the metal bob of a simple pendulum is replaced by a wooden bob, then its time period will

If the bob of a simple pendulum is made to osciliate in some fluid of density greater than the density of air ( density of the bob > density of the fluid ), then time period of the pendulum increased or decrease.

Assertion: The bob of a simple pendulum is a full of water if a fine hole is made at the bottom of the of the ball , then the time period will no more remain constant Reason : The time period of simple pendulum does not depend open mass
