Two spheres of radii \( \mathrm{R}_{1} \& \mathrm{R}_{2} \) respectively are charged and joined by a wire. The ratio of electric field of spheres at any point equal distant from both the spheres is:
a. \( \left(\frac{R_{2}}{R_{1}}\right)^{2} \)
b. \( \left(\frac{\mathrm{R}_{1}}{\mathrm{R}_{2}}\right)^{2} \)
c. \( \frac{R_{2}}{R_{1}} \)
d. \( \frac{\mathrm{R}_{1}}{\mathrm{R}_{2}} \)
