Question

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 the ploughing the length of the field​

Answer 1

Answer:

w=f×s

Explanation:

w=140n×15m,w=2100j

Answer 2

Force (F) = 1400 N.

Distance (s) = 15m.

$\LARGE{\bf{\underline{\underline{TO \ FIND:-}}}}$

The work done (w)

$\LARGE{\bf{\underline{\underline{SOLUTION:-}}}}$

We can use the formula for work done:

$\mapsto \sf{\green{W=Fs}}$

Where:

F is force.

s is distance.

Substituting the values, we get:

$\to \sf W=140 \times 15$

$\leadsto \sf{\red{2100J}} \bigstar$

∴Work done is 2100 J.
