Question

2) The SI unit of G (universal Gravition constant) is

i] kg²s-²
ii] Nm²kg²
iii] Nm²kg-²
iv] Nm-²kf-²​

Answer 1

Explanation:

In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. ... The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2.
