The correct answer is:
A represents the P.E., B the total energy and C the K.E.
The K.E. is always positive.
The curve C represents the K.E. Both P.E. and total energy are positive but
As P.E. = 2 (Total energy)
B represents the total energy and A represents the P.E.
The curve C represents the K.E. Both P.E. and total energy are positive but
As P.E. = 2 (Total energy)
B represents the total energy and A represents the P.E.
