Question

At what height from the surface of the earth will the value of g reduced by 36% from the value of g at the surface.Radius of earth os 6400 km

Answer 1

concept of gravitation

Answer 2

⭐⭐⭐ Hey mate!!!⭐⭐⭐

__________________________________________________________

⚡Let the new acceleration due to gravity at that be g'

Now ,

⚡g' = 64% of g

⚡g' = 64g/100

⚡g'= g/(1+h/Re)^2

⚡64g/100 = g/(1+h/Re)^2

⚡(1+h/Re)= 10/8

⚡1+h/Re =5/4

⚡h/Re = 5/4-1

⚡h/Re = 1/4

⚡h = Re/4

Hope it will help you....✌️✌️
