NDA || GRAVITATION || QUIZ

When a missile is launched with a velocity less than the escape velocity then what is the sum of its kinetic and potential energy?

The dimensional formula of gravitational constant G, is

If radius of the earth were to shrink by 1%, its mass remaining the same, g would decrease by nearly -

The acceleration due to gravity ‘g’ for objects on or near the surface of the earth is related to the universal gravitational constant ‘G’ as (‘M’ is the mass of the earth and ‘R’ is its radius):

Calculate the depth’ at which the value of acceleration due to gravity becomes  times the value at the surface. [R = radius of the earth]
