Answer:
Option C
Explanation:
Let the potential energy of rock A be represented as Pa
And the potential energy of rock B be represented as Pb
Pa = ma * g * h
Pb = mb * g*h
ma = 2 * mb
Thus, Pa = 2 mb * g*h
Pa/Pb = 2 mb * g*h/mb * g*h
Pa/Pb = 2
Pa = 2 * Pb
The energy pf rock A is two times the energy of rock B.
OR
Pb = Pa/2
Hence, option C is correct
