Question

Write the derivation of acceleration due to gravity?

Answer 1

Answer:

Acceleration Due to Gravity (g)

Symbol g

Dimensional Formula M0L1T-2

SI Unit ms-2

Formula g = GM/r2

Values of g in SI 9.806 ms-2

Values of g in CGS 980 cm s-2ravity is the force with which the earth attracts a body towards its centre. Let us consider two bodies of masses ma and mb. Under the application of equal forces on two bodies, the force in terms of mass is given by:

mb = ma [aA/aB] this is called an inertial mass of a body.

Under the gravitational influence on two bodies,

FA = GMmA/r2,

FB = GMmB/r2,

mB = [FB/FA] × mA
