Question

Two,weights of 5 kg and 10kg are placed on a horizontal table of height 1.5 m. Which weight will have more potential energy?

• A. 5 kg
• B. 10 kg
• C. Both will have equal energy
• D. None of the above

Answer 1

The correct option is B 10 kg

We know that $PE=mgh$

$\Rightarrow PE$ $\alpha$ $m$

So the $10kg$ weight will have more$PE$ than $5kg$ weight

$\Rightarrow P{E}_{10}=10\times 10\times 1.5=150J$

$\Rightarrow P{E}_5=5\times 10\times 1.5=75J$

$\Rightarrow P{E}_{10}>P{E}_5$

Hence, correct answer is option $B$
