Question

Let VG and EG denote gravitational potential and field respectively, then choose the wrong statement.
VG=0,EG=0
VG≠0,EG=0
VG=0,EG≠0
VG≠0,EG≠0

Answer 1

the third option  is wrong.

d VG / d x = EG = 0  =  gradient of potential in distance is the field.

So  if VG = 0 then EG = 0  This is true.
If  VG ≠ 0 then EG can still be 0.
If  VG≠ 0 then it is also possible that EG ≠ 0.

But if VG = 0, then  it is not possible that EG ≠ 0.
