The difference in the acceleration due to gravity at the pole and equator is ( g= acceleration due to gravity, R= radius of earth, = latitude, = angular velocity, 0^ =1, 90^ =0 )
Options
- AR ^2 ^2
- BR ^2
- CR ^2 g^2
- D^2
Correct answer
B. R ^2
Step-by-step solution
Acceleration due to gravity at a place of latitude due to rotation of earth is g^ =g-R ^2 ^2 At equator, =0, 0=1 g^ =g_e=g-R ^2 At poles, =90, 90=0 g^ =g_p=g g_p-g_e=g- (g-R ^2 )=R ^2
