Question

describe the gravitational feild itensity​

Answer 1

$\boxed{\huge{\purple{\mathcal{Answer}}}}$

$<b>$

The gravitational field intensity (EG) or (g) is the force on a unit mass at a point in the field.

Since the force (F) on a body of mass m in a gravitational field of a body of mass M = GMm/r2 .

you can see that the force per unit mass is given by F/m. So:

Gravitational Field Intensity (EG) = (g) = F/m = GM/r2

The units for EG are N kg -1 or since F = ma, F/m = a and so EG may be expressed in ms -2

Answer 2

The gravitational field intensity (EG) or (g) is the force on a unit mass at a point in the field. Since the force (F) on a body of mass m in a gravitational field of a body of mass M = GMm/r2 . you can see that the force per unit mass is given by F/m. So: Gravitational Field Intensity (EG) = (g) = F/m = GM/r2.
