please..provide explaination.please solve both Q.​

Answer 1

33.flux entering=Ф1

flux leaving=Ф2

Ф1 and Ф2 have opposite signs as one is leaving and other is entering

Ф=q/e

q=Фe

=(Ф2-Ф1)e

34.flux depends only on charge enclosed

as the 2 shells are concentric therefore charge enclosed remains same and hence flux in the 2 cases is same ie 50 V-m
