A uniform electric field E_0 exists in a region at angle 45^(@) with the x - axis. There are twom point A(a, 0) and B(0,b) having potential V_A and V_B, respectively, then .

Answer»

`a lt b`
`a GT b`
`a gt b`
`a = b`

SOLUTION : EQUIPOTENTIAL surfaces will be inclined at `135^(@)` to the x - axis. If `a gt b`, then while moving from B to A, we are going in the direction of field, i.,e., from high to LOW potential. Similarly, options `b,c and d` are correct.
