Two conducting hollow spheres of radius 5 mm and 10 mm respectively are placed such that their center to center distance is 20 cm. If they are connected by a conducting wire, then the ratio of electric field \(\left(\frac{E_1}{E_2}\right)\) just outside the surface will be:
(1) 1/2
(2) 2/1
(3) 1/4
(4) 4/1
