    If the symbols V and E represents the gravitational potential and gravitational fieldat a point. It is possible to have

    A) V = 0 and E = 0                  

    B) \[V\ne 0\] and \[E\ne 0\]

    C) V= 0 and \[E\ne 0\]        

    D) \[V\ne 0\]and E =0

    Correct Answer: C

    Solution :

    As,\[E.d=\Delta V=V\]\[\Rightarrow \]\[Ed\cos \theta =\Delta V=V\] For\[\Delta V=V=0\]may be E = 0 but \[\theta \ne 0\] or may\[\cos \theta =0\]but \[E\ne 0\] Thus, the gravitational potential can be zero, while \[E\ne 0\]
