Question

A pair of bullocks exert a force of 140N on a plough. The feild being ploughed is 15m long. How much work is done in ploughing the feild?

Answer 1

Work done = Force . Distance

W = 140 . 15 = 2100 joules

Answer 2

$\textbf{\underline{\underline{According\:to\:the\:Question}}}$    

Force = 140 Newton

Displacement = 15m (s)

Now

Work done

= F × S

= 140 Newton × 15m

= 2100 Joule
