The acceleration of a charged particle in a uniform electric field is : (where s
The acceleration of a charged particle in a uniform electric field is : (where specific charge of a particle \( \left.=\frac{q}{m}\right) \)
- A. proportional to its charge only
- B. inversely proportional to its mass only
- C. proportional to its specific charge
- D. inversely proportional to specific charge
Step-by-step solution
From Newton's second law and Lorentz force, F = qE, so a = F/m = qE/m = (q/m)E. Since E is constant, a ∝ q/m, i.e., specific charge.
