At what altitude above the earths surface would the acceleration due to gravity be one-fourth?

diffcult

Correct option is

Given,

 

We know that, acceleration due to gravity at height h from the surface of the earth.

 

Hence,

  

 

where, R is the radius of the earth.

Q1

A body weigh 200 N on the surface of the earth. How much will ut weigh half way down to the centre of the earth ?

Q2

Find gravitational field at a distance of 2000 km from the centre of earth.(Given

Q3

R  is the radius earth,

 is its angular velocity and  is the value of g at the poles. The effective value of g at a latitude  is

Q4

The weight of a body on the surface of the earth is 63 N. What is the gravitational force due to the earth at a height equal to half the radius of the earth?

Q5

The acceleration due to gravity at a height 1 km above the earth is the same as at a depth d below the surface of earth. Then

Q6

The planets with radii

 have densities  respectively. Their atmospheric pressure are  respectively. Therefore, the ratio of masses of their atmospheres, neglecting variation of g within the limits of atmosphere is

Q7

Weightlessness experienced while orbiting the earth in spaceship, is the result of

Q8

What will be the acceleration due to gravity at depth d, where g is acceleration due to gravity on the surface of earth?

Q9

The height vertically above the earth’s surface at which the acceleration due to gravity g with depth h from the surface of the earth?

Q10

The mass of the moon is (1/6)th of  the earth but fact that
