Question

A particle is taken to a height r above the earth's surface, where r is the radius of the earth. The acceleration due to gravity there is ??

Answer 1

· If R is the radius of the earth and g the acceleration due to gravity on the earth's surface, the mean density of the earth is. (a)4piG/3gR (b)3piR/4gG.

Answer 2

so its initial velocity equal to zero B squared plus 2 squared equal to 2 years equal to the acceleration and by a body
