An object of mass m when raised to a height h possesses potential energy of 200J. Find the new potential energy if the same object is raised to a height 3h.
Answers
potential energy =mgh=200j
new height=3h
new potential energy=3*200=600j
i hope this helps u...
The new potential energy will be 600 Joule.
Calculation:
It is given that,
Case I
Mass of the object = m
Height upto which object is raised = h (initial height)
Potential energy of the object = 200 J (initial potential energy)
In this case, we can write that,
P.E = mgh
200 = mgh ---- eq. (1)
Case II
Mass of the object = m
New height upto which the object is raised (h') = 3h
New potential energy (P.E') = ?
Now, by applying the formula of potential energy, we can write,
(P.E') = mgh'
(P.E') = mg(3h)
P.E' = 3mgh
From eq. (1), we can write that mgh = 200
Therefore,
P.E' = 3 × 200
P.E' = 600 Joule
Therefore, the new potential energy is the same object of mass 'm' is raised to a height of 3h will be 600 Joule.
