Weight of the body=9.8 N
Acceleration due to gravity on earth=9.8 m/s²
Hence,mass of the body=W/g
=1 kg
Force exerted on body=20N
We know,
F=ma
a=F/m
a=20/1
a=20 m/s²
Acceleration due to gravity on earth=9.8 m/s²
Hence,mass of the body=W/g
=1 kg
Force exerted on body=20N
We know,
F=ma
a=F/m
a=20/1
a=20 m/s²

Mass of body = Weight / g
= 9.8 N / 9.8 m/s²
= 1 kg
Mass of the body is 1 kg
Acceleration = F / m
= 20 N / 1 kg
= 20 m/s²
Acceleration of body is 20 m/s²
= 9.8 N / 9.8 m/s²
= 1 kg
Mass of the body is 1 kg
Acceleration = F / m
= 20 N / 1 kg
= 20 m/s²
Acceleration of body is 20 m/s²
