Charge passing through a conductor of cross-section area A = 0.3 m2 is given by q = 3t2 + 5t + 2 in coulomb, where t is in second. What is the value of drift velocity at t = 2s? (Given, n = 2x 1025/m3)

Given q=3t2+5t+2i=dqdt=6t+5t=2 sec i=17But i=neAvdvd=ineAsubstituting the value we get vd=1.77x10-5m/s

Detailed Solution

$Given q = 3 t^{2} + 5 t + 2$

$i = \frac{dq}{dt} = 6 t + 5$

$t = 2 \sec i = 17$

$But i = {neAv}_{d}$

$v_{d} = \frac{i}{neA}$

substituting the value we get $v_{d} = 1.77 x 10^{- 5} m / s$
