what is the relation between g and G ?

Answer.
    F = ma...............1
F = G*M*m/d2......2
By 1 and 2
ma = G*M*m/d2
On upward or downward motion under the influence of gravity a=g
So,

Why is it that an iron nail sinks whereas a ship floats in water? Please explain.

As the density of an iron nail is more than that of water, the nail sinks in water. This is understandable. But a huge ship made of iron floats. This is because of its shape. A ship is hollow in the middle. Whe...

Define thrust and pressure. Give their SI units.

Thrust is the force acting nornally on a surface. Its SI unit is newton (N). Pressure is force per unit area. Its SI unit is pascal (P) or newton per square metre (N/m 2).
