Question

The SI unit of gravitational constant (G) is

N/m2

Nm2/kg2

Nkg2/m2

​

Answer 1

Newtons kg

In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”.

Answer 2

The SI unit of gravitational constant (G) is Nkg2/m2.
