Question

Which of the following object has higher potential energy?

• A. Mass $=10kg$ $g=9.8m{s}^{-2}$ $h=10m$
• B. Mass $=5kg$ $g=9.8m{s}^{-2}$ $h=12m$
• C. Mass $=8kg$ $g=9.8m{s}^{-2}$ $h=100m$
• D. Mass $=6kg$ $g=9.8m{s}^{-2}$ $h=20m$

Answer 1

The correct option is C Mass $=8kg$ $g=9.8m{s}^{-2}$ $h=100m$

Potential Energy$=mgh$

i) $P.E.=980J$

ii) $P.E.=588J$

iii) $P.E.=7840J$

iv) $P.E.=1176J$

Out of given options case 3 has highest potential energy
