At a height ' R ' above the earth's surface the gravitational acceleration is ( R = radius of earth, g = acceleration due to gravity on earth's surface)
Options
- Ag
- Bg 8
- Cg 4
- Dg 2
Correct answer
C. g 4
Step-by-step solution
Acceleration due to gravity is given by aligned & g ^ = GM r ^2 = GM ( R + h )^2 = GM (2 R )^2 & = GM 4 R ^2 = g 4 aligned
