The elctric potential in a region is given by, `v = 3x^(2) + 4x`. An electron is placed at the origin will experience:

Options

A. force along positive `x`
B. force along negative `x`
C. zero force
D. none of these

Answer

A

Explanation

`E_(x) = - (dv)/(dx) = - (6x +4)`
`E_(y) = 0 E_(s) = 0`
At origin `E_(x) = - 4`
Thus, electorn will experience force in the direction opposite to electirc field i.e., in `+x` direction.
