A particle of mass 2 g and charge 6 C is accelerated from rest through a potential difference of 60 V . The speed acquired by the particle is

Step-by-step solution

For the particle, m =2 ~g , q =6 C , ~V =60 ~V The momentum of the particle is aligned & p = 2 mq _ V mv = 2 mq _ V & Speed, v = 2 q _ V ~m = 2 6 10⁻⁶ 60 2 10⁻³ & =0.6 ~ms ⁻¹ aligned
