Question

mass of a body raised at height of 10 m and possessing potential energy of 49 j is?​

Answer 1

Let mass of body be m

• Height=h=10m
• Potential energy=49J
• Acceleration due to gravity=g=10m/s^2

We know

$\boxed{\sf E_P=mgh}$

$\\ \sf\longmapsto 49=10(10)m$

$\\ \sf\longmapsto 100m=49$

$\\ \sf\longmapsto m=\dfrac{49}{100}$

$\\ \sf\longmapsto m=0.49kg$
