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 1 N (1 unit = 1 metre)?

• A. 1 J
• B. 3 J
• C. 5 J
• D. 7 J

Answer 1

The correct option is C

5 J

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
$=5m\times 1N=5J$
