5. Two boys A and B are sitting at two points in a field. Both boys are sitting near assemblage of charged balls each carrying charge +3e. A throws 100 balls per second towards B while B throws 50 balls per second towards A. Simultaneously find the current at the mid-point of A and B. a ) i = 3 . 4 × 10 - 17 A f r o m A t o B b ) i = 2 . 4 × 10 - 17 A f r o m A t o B c ) i = 3 . 4 × 10 - 17 A f r o m B t o A d ) N o n e o f t h e a b o v e Share with your friends Share 3 Sandeep K. Gupta answered this Dear Student, Consider the mid point of A and BTotal charge per second flows from A to B is Q1=1003e and form B to A is Q2=503e.Because current flows in the direction of positive charge hence net charge per second which generatenet current will beQ=Q1-Q2=503e from A to BSo, current will be i=Qt=503e=150×1.6×10-19 A i=2.4×10-17 A from A to B.
