Question

A force of 2N act on (a)a body whose mas is 2 kg &(b)a body whose weight is 2N.Fnd their rspectve aceleretion.

Answer 1

If no other forces acts on these bodies:

For body (A):

F=m*a

a=2N/2Kg

a=1m/s^2

For body (B):

F=m*a

the mass of body B is 2N/9.81m/s^2 = 0.204Kg

a=2N/0.204Kg

a=9.8m/s^2

Answer 2

F=ma

a) m = 2, F = 2

so, a = 1 m/sq. sec

b) Weight = mg

W = 2,m=2/g

F=ma

F=2,m=2/g

so, a = g = 9.8 m/sq.sec.
