AP EAMCET · PHYSICS · Current Electricity
Drift speed \((v)\) varies with the intensity of electric field \((\mathrm{E})\) as per the relation
- A \(v \propto \mathrm{E}\)
- B \(v \propto \frac{1}{\mathrm{E}}\)
- C \(v \propto \mathrm{E}^2\)
- D \(v \propto \mathrm{E}^{-2}\)
Answer & Solution
Correct Answer
(A) \(v \propto \mathrm{E}\)
Step-by-step Solution
Detailed explanation
The drift speed is given by \(v_d=\left(\frac{c E}{m}\right) و \Rightarrow v_d \propto E\)
