Question

4. A pair of bullocks exerts a force
of 140 N on a plough. The field
being ploughed is 15 m long.
How much work is done in
ploughing the length of the field?​

Answer 1

Answer:

Work done by the bullocks is given by the expression : <br> Work done = Force

Displacement <br>

<br> Where <br> Applid Force, F = 140 N <br> Displacement, d = 15 m <br>

<br> Hence, 2100 J of work is done in ploughing the length of the field.
