Vedclass · Answer

(D) seconds pendulum is a pendulum whose time period is $2 	ext{ s}$.In a space laboratory orbiting the Earth,the laboratory and everything inside it are in a state of weightlessness.This means the effective acceleration due to gravity $(g_{	ext{eff}})$ inside the laboratory is $0$.The formula for the time period of a simple pendulum is $T = 2\pi \sqrt{\frac{l}{g_{	ext{eff}}}}$.Substituting $g_{	ext{eff}} = 0$ into the formula,we get $T = 2\pi \sqrt{\frac{l}{0}} = \infty$.Therefore,the time period of the pendulum will be infinite.

$A$ seconds pendulum is placed in a space laboratory orbiting round the Earth at a height $3R$ from the Earth's surface. The time period of the pendulum will be ($R =$ radius of Earth).
