The height ' h ' above the earth's surface at which the value of acceleration due to gravity ( g ) becomes ( g 3 ) is ( R = radius of the earth)
Options
- A( 3 +1) R
- B( 3 -1) R
- C3 R
- D3 R
Correct answer
B. ( 3 -1) R
Step-by-step solution
We know that, aligned & g _ h = g ( R R + h )^2 & For g_h= g 3 & g 3 =g ( R R+h )^2 & 1 3 = R R + h & 3 R = R + h & h=( 3 -1) R aligned
