A body weight $500 \,N$ on the surface of the earth. How much would it weigh half way below the surface of the earth ....... $N$
$125$
$250$
$500$
$1000$
The mass and the diameter of a planet are three times the respective values for the Earth. The period of oscillation of a simple pendulum on the Earth is $2\,s$. The period of oscillation of the same pendulum on the planet would be
$Assertion$ : Space rocket are usually launched in the equatorial line from west to east
$Reason$ : The acceleration due to gravity is minimum at the equator.
The variation of acceleration due to gravity $g$ with distance $d$ from centre of the earth is best represented by ($R =$ Earth's radius)
A body weighs $250\,N$ on the surface of the earth. ....... $N$ will it weigh half way down to the centre of the earth .
