Question

if a charge flown through a cross section of wire in one one direction during 0 to t is given by q= 3 sin (3t) then find out the amount of charge flowing through the wire till t = (pi/6) seconds ​

Answer 1

 Δq = 3

Explanation:

Given: Charge flown through a cross section of wire in one direction during 0 to t is given by q = 3 sin (3t).

Find: Amount of charge flowing through the wire till t = (π/6) seconds

Solution:

Δq = total charge flown between t = 0 to π/6

     = 3 |sin3t| .... t ranges from 0 to π/6

     = 3 [sin π/2]

     = 3 [1] as Sin π/2 is sin 90 which is one.

 Δq = 3
