(c) P.E. = 2T.E.

?P.E. = 2E0

Note : In case of circular motion of satellite around earth / planets revolving around sun/electrons revolving in circular orbit P.E. = 2 T.E. and |K.E.|= |T.E.|]

Although P.E. is 2E and K.E. is >0 net sum becomes greater than 2E but T.E. is E so how the T.E. = P.E. +K.E.
