QNEET-2020-Ph-706: NEET 2020 Physics - Class 12 NEET-2020-Ph-706 Solution: A charged particle having drift velocity \(7.5 10^{-4}\…

A charged particle having drift velocity 7.5×10−4 ms−17.5 \times 10^{-4}\ \text{ms}^{-1} in an electric field of 3×10−10 Vm−13 \times 10^{-10}\ \text{Vm}^{-1} has a mobility in m2V−1s−1m^2 V^{-1} s^{-1} of: 2.5×1062.5 \times 10^6 2.5×10−62.5 \times 10^{-6} 2.25×10−152.25 \times 10^{-15} 2.25×10152.25 \times 10^{15}

Multiple Choice Options

  • A 2.5 ×\times _ 10 6
  • B 2.5 ×\times _ 10 -6
  • C 2.25 ×\times _ 10 -15
  • D 2.25 ×\times _ 10 15

Step-by-Step Verified Solution

The relation between the mobility and drift velocity is, Mobility, _ = _ d E = 7.5 _ 10 _ 4 3 _ 10 _ 10 = 2.5 _ 10 6 m 2 V _ 1 s _ 1
