The electric potential at a space point $\mathrm{P}\mathrm{ }\left(\mathrm{x},\mathrm{ }\mathrm{y},\mathrm{ }\mathrm{z}\right)$ is given as $\mathrm{V}={\mathrm{x}}^2+{\mathrm{y}}^2+{\mathrm{z}}^2$. The modulus of the electric field at that point is proportional to

• Correct answer
  A

  ${\mathrm{V}}^{\frac{1}{2}}$
• B

  $\mathrm{V}$
• C

  ${\mathrm{V}}^{\frac{3}{2}}$
• D

  ${\mathrm{V}}^2$

Hence, the correct answer is option: 'A'.
