In an uniformly charged sphere of total charge Q and radius R , the electric field E is plotted as function of distance from the centre. The graph which would correspond to the above will be

Step-by-step solution

Electric field inside the uniformly charged sphere varies linearly, E= k Q R³ r,(r R) while outside the sphere, it varies as inverse square of distance, E= k Q r² ;(r R) which is correctly represented in option (c).
