The electric potential at certain point is given by,v=-7.5x²-3x ,where v is in volts and x is in meters. then the electric field at that point is -(15x+3).

Given,

The electric potential at certain point is given by,

v=-7.5x²-3x .

where v is in volts and x is in meters.

We know,

electric potential (v) =electric field ×radius

Electric potential is defined as the amount of work needed to move a charge from reference point to the specific point against an electric field.

Also, electric field (E) =dv/dx

Electric field at a point is the force experienced by the unit positive charge placed at that point.

E=d(-7.5x²-3x)/dx=-15x-3

Thus ,the electric field at that point is given by -(15x+3 ).
