Answer 1

S.I unit of force is Newton (N).

One Newton is that force which when acting on a body of mass 1 kg, produces an acceleration of 1 m s^-2 in it.

C.G.S unit of force is dyne.

One dyne is that force which when acting on a body of mass 1 gram, produces an acceleration of 1 cm s^-2 in it.

1 Netwon = `10^5` dyne
