NEET · Physics · STD 12 - 3. current electricity
A charged particle having drift velocity of \(7.5 \times 10^{-4}\, ms ^{-1}\) is an electric field of \(3 \times 10^{-10}\, Vm ^{-1}\) has a mobility in \(m ^{2} V ^{-1} s ^{-1}\) of
- A \(2.25 \times 10^{-15}\)
- B \(2.25 \times 10^{15}\)
- C \(2.5 \times 10^{6}\)
- D \(2.5 \times 10^{-6}\)
Answer & Solution
Correct Answer
(C) \(2.5 \times 10^{6}\)
Step-by-step Solution
Detailed explanation
\(\mu=\frac{v_{d}}{E}=\frac{7.5 \times 10^{-4}}{3 \times 10^{-10}}\) \(=2.5 \times 10^{6}\)
