Question

An ant drags a piece of sweet from origin (0,0) to (3,4) in the co-ordinate axes. What is the work done by the ant if it applies a force of $1N$?

• A. $7J$
• B. $3J$
• C. $6J$
• D. $5J$

Answer 1

The correct option is D $5J$

Displacement of the sweet from (0,0) to (3,4) is equal to its displacement from the origin.
Displacement $=\sqrt{3^2+4^2}$
$=\sqrt{9+16}=5m$
Force applied by the ant is $1N$
Since, Work $=Force\times displacement$
Work done by the ant
$=5m\times 1N=5J$
