Draw the graph showing variation of gravitational acceleration due is depth and altitude from the earth's surface

Define Earth's gravitational acceleration

(a) Assuming the earth to be a sphere of uniform density, calculate the value of acceleration due to gravity at a point, 1600 km above the earth, (b) Also find the rate of variation of acceleration due to gravity above the earth's surface. Radius of earth =6400 km, g =9.8 m//s^(2) .

Discuss the variation of g with depth and derive the necessary formula. OR Show that the gravitational acceleration due to the earth at a depth d from its surface is g_d= g[1- frac(d)(R)] , where R is the radius of the earth and g is the gravitional acceleration at the earth's surface. OR Discus the variation of acceleration due to gravity with depth 'd' below the surface of the earth OR Derive an expression for acceleration due to gravity at depth 'd' below the surface of earth

Derive an expression for the acceleration due to gravity at a depth d below the earth'ssurface

The value of gravitational acceleration at a height equal to radius of earth, is

The gravitational potential due to the earth is minimum at

Discuss the variation of acceleration due to gravity with altitude.

Let omega be the angular velocity of the earth's rotation about its axis. Assume that the acceleration due to gravity on the earth's surface has the same value at the equator and the poles. An object weighed at the equator gives the same reading as a reading taken at a depth d below earth's surface at a pole (dlt ltR) . the value of d is-

Distinguish between universal gravitational constant and gravitational acceleration of the earth.
