Question

If the values of force and length are increased four times, then the unit of energy will be increase by:

• A. $4times$
• B. $2times$
• C. $8times$
• D. $16times$

Answer 1

The correct option is D $16times$

Energy $E=F\times d$

So, if the values of force and length are increased by four times, the energy gets increased by a factor of $16$.
