Physics Question on Electric Field

Given the potential difference V(x)=−x2yV(x) = -x^2 y volts, find the electric field at the point (1, 2).

A

i^+4j^ V/m\hat{i} + 4\hat{j} \, \text{V/m}

B

−4i^−j^ V/m-4\hat{i} - \hat{j} \, \text{V/m}

C

4i^+j^ V/m4\hat{i} + \hat{j} \, \text{V/m}

D

4i^−j^ V/m4\hat{i} - \hat{j} \, \text{V/m}

Answer

4i^+j^ V/m4\hat{i} + \hat{j} \, \text{V/m}

Explanation

Solution

The correct option is(C):4i^+j^ V/m4\hat{i} + \hat{j} \, \text{V/m}
