Question

A force of 5 N acts on a body of 9.8 N . What is its acceleration?

Answer 1

for body of 9.8N

Its mass,m=f/g=9.8/9.8=1kg
[ where g is acceleration due to gravity, g=9.8 m/s² on earth ]

Take, Force= F
mass=m
acceleration=a

F=ma
a=F/m
a=5/1=5m/s²

Answer 2

Mass of body = Weight / g
= 9.8 N / (9.8 m/s²)
= 1 kg

Acceleration of body = Force acting on body / Mass of body
= 5 N / 1 kg
= 5 m/s²

Acceleration of body is 5 m/s²
