A particle of mass 0.5 g and charge 10 C is subjected to a uniform electric field of 8 NC ⁻¹ . If the particle is initially at rest, the velocity of the particle after a time of 5 seconds is
Options
- A5 ~ms ⁻¹
- B0.5 ~ms ⁻¹
- C8 ~ms ⁻¹
- D0.8 ~ms ⁻¹
Correct answer
D. 0.8 ~ms ⁻¹
Step-by-step solution
For charged particle, m =0.5 ~g , q =10 c , E =8 NC ⁻¹, t =5 ~s Acceleration, a = qE m Velocity after time t is aligned & v=u+a t=0+ ( q E m ) . t & = 10 10⁻⁶ 8 5 0.5 10⁻³ =0.8 ~ms ⁻¹ aligned
