potential energies will be maximum at
(a) ground
(b) highest point
c. at centre whan going up
d at all point​

Answer 1

Answer:

at the centre

Explanation:

because at top potential energy is maximum ac to mgh and at bottom kinetic energy is max and at other points if kE is increasing then pE is decreasing and viceversa but at centre both are equal
