Question

. If acceleration due to gravity is 10 m/s², what will be the gravitational potential

energy of a body of mass 1 kg kept at a height of 5 m?​

Answer 1

Explanation:

We know that,

Ep = mgh

Here,

m = 1kg; g = 10 m/s2; h = 5m

So, Ep = 1kg*10m/s2*5m

= 50J

So, the potential energy is 50J (Ans.)

Answer 2

Question:

If acceleration due to gravity is 10 m/s², what will be the gravitational potential energy of a body of mass 1 kg kept at a height of 5 m?

Answer :

We have formula

$PEg = mgh.$

$Where, \\ </p><p> PE = potential \: energy \: due \: to \: gravity \\ </p><p> g \: = acceleration \: due \: to \: gravity \: \\ </p><p> m \: = \: mass \: </p><p> h \: = \: distance \: above \: a \: surface \: (such \: as \: the \: ground \: )</p><p>$

$\: given = > \\ \\ \\ PE =? \\ </p><p> \\ g = 10m/s² \\ </p><p> \\ m = 1kg \\ </p><p> \\ h= 5 m \\ </p><p>$

$PEg = mgh. \\ \: = 1 \times 10 \times 5 = 50 \:joules$
