Gravitational Fields | MCQs

Explanation

In deep space far from massive objects, the gravitational pull becomes negligible, effectively making gravity zero.

This is why astronauts experience weightlessness in such regions.

Explanation

• The formula for the period of a pendulum is T = 2π√(l/g), where l is the length of the pendulum and g is the acceleration due to gravity.
• Since the mass and diameter are doubled, the acceleration due to gravity (g) on the planet will be half that of Earth.
• Therefore, the new period of oscillation will be √2 times the period on Earth, meaning if it was a second's pendulum on Earth, it will be 2√2 seconds on the planet.
