Question

An electron at rest has a charge of 1.6 x 10-19
C. It starts moving with a velocity v = c/2,
where c is the speed of light, then the new
charge on it is -
​

Answer 1

Answer:2.4*10^-13 C

Explanation:Dear Student

According to the question:The amount of charge = 1.6*10^(-19)C

Velocity  =c/2= 1.5*10^6 m/sec.

Then the new charge = 1.6*10^-19*1.5*10^6 C

                                     = 2.4*10^-13 C

                                                                                Hope it helps

                                                                                With Regards

Answer 2

Explanation:

It is given that,

Charge on an electron is $1.6\times 10^{-19}\ C$

It starts moving with a velocity v = c/2,  where c is the speed of light. We need to find the new charge on it.

Charge is quantized. It means that the charge on an electron is given by :

q = ne

n is no of electrons

It means that the charge is independent of the velocity. So, if the electrons starts moving with a velocity of c/2, then the new charge remains the same i.e. $1.6\times 10^{-19}\ C$.
