10 Fields

Question 1

Gravitational field is given by ?

A gravitational field is formed by?

Answer 1

g=GM/r^2

A massive spherical body of mass M

Question 2

What is gravitational potential energy?

Answer 2

Gravitational pontential energy of two bodies is the work that is done in bringing two bodies to their present position from when they were infinitely far apart.

Question 3

What is Gravitational potential (Vg)

Answer 3

Gravitational potential at a point p in a gravitational field is the workdone per unit mass in bringing a small point mass M from infinity to point p.

Vg = V/m

Vg = -Gm/very 2

Question 4
