Question

If height is doubled and mass is halved, the potential energy
A. Increase
B. decrease
C. Reamin same
D. become Half​

Answer 1

Explanation:

Given,

h = 2h

m = m / 2

potential energy = mgh

= g × 2h × m

__

2

potential energy = mgh

If height is doubled and mass is halved, the potential energy remains the same.

Answer 2

Answer:

Option C.

Explanation:

To find:

• Potential energy = ?

Formula used:

• Potential energy (P.E) = mgh

Solution:

Given info:

If the mass is halved i.e, m = m/2

And, if the height is doubled i.e, h = 2h

So, we know P.E = mgh

(so put the values)...

$= = > potential \: energy \: = \: \: \frac{m}{2} \times g \: \times \: \: 2h \:$

==> P.E = mgh

Hence, the ans is option (C) remain same ✔.

Hope it helped you dear...
