Question

A boy is carrying a school bag of 3 Kg mass on his back and moves 200 m on a levelled road. The work done against the gravitational force will be (take g= 10 m/s2)

A.
6000 J

B.
6 J

C.
Zero

D.
0.6 J​

Answer 1

Answer:

6000J

Explanation:

Mass = 3kg

Distance = 200m

Acceleration due to gravity = 10m/s²

Force = Mass × acceleration

= 3 × - 10

= -30m/s² (Moving upwards results in negative acceleration)

Work done = Force × Displacement

= -30 × 200

= -6000 J (or) 6000J as it is mentioned in the question that calculate the Work done against the Gravitational force.
