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,

mg = G*M...

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}).
