Solution

The correct option is D
$98 J$

Potential energy is mathematically represented by the formula
$P.E. = m \times g \times h$
where m is the mass,
g is acceleration due to gravity and
h is the height in meters.
$Potential Energy = 1$ $\times 9.8 \times 10$
$= 98 J$

To what height should an object of mass $2 kg$ be raised so that its potential energy is $980 J$ ?(Take, $g = 9.8 m s^{- 2}$ )

We know that If a ball of mass $1 k g$ is kept at a height $10 m$ possess potential energy $m g h$ i.e. $(1 \times 10 \times 10) = 100$ J. (Taking earth surface as reference, where m = mass of object, g = acceleration due to gravity, h = height of object from earth surface.) what will be the kinetic energy of the ball when the ball is allowed to freely fall from a height $10 m$ just before it hits the ground? (take g = 10 $m / s^{2}$ and neglect air drag)

If a ball of mass 1 kg is falling from a height 10 m. What will be the kinetic energy of the ball when it hits the ground?( take g = 10 m/s²) and neglect air drag.

What would be the gravitational potential energy of an object whose mass is 1 kg and is at a height of 10 m?(take g=9.8 ms−2)

The correct option is D 98 J Potential energy is mathematically represented by the formula P.E. = m×g×h where m is the mass, g is acceleration due to gravity and h is the height in meters. Potential Energy = 1 ×9.8×10 = 98 J
