Question

Orbital velocity derivation class 11 maritnation

Answer 1

i think u are asking for gravitation 
so here we go
the gravitation force offered by the earth is equal to = GMm/r2 
and the centripetal force given to the body is equal to = mv2/r
so after eqauting the equations we get     v2=GM/r 
hence the orbital velocity is independent of the mass of the satellite
