Which of the following options are correct ?A. Acceleration due to gravity decreases with increasing altitude.B. Acceleration due to gravity increases with increasing depth (assume the earth to be a sphere of uniform density).C. Acceleration due to gravity increases with increasing latitude.D. Acceleration due to gravity is independent of mass of the earth. |

Answer» Correct Answer - A::C At altitude `h`, `g_(h) = (gR^(2))/((R + h)^(2)) = (g)/((1 + h//R)^(2))` As `h` increases, `g_(h)` decreases. At depth `d`, `g_(d) = g (1- (d)/(R ))`, As `d` increases, `g_(d)` decreases At latitude `lambda`, `g_(lambda) = g - R omega^(2) cos^(2) lambda`, As `lambda` increases, the value of `cos lambda` decresas so `g_(lambda)` increases On surface of earth, `g = (GM)/(R^(2))`, i.e., `g` depends on mass `M` of the earth. |
