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 = 2 \(\times\) 1025/m3)
- 0.77 \(\times\) 10-5 m/s
- 1.77 \(\times\) 10-5 m/s
- 2.08 \(\times\) 105 m/s
- 0.57 \(\times\) 105 m/s
Answer
(B) 1.77 10 -5 m/s
