Question

calculate the amount of work done to carry 4 MC of charge from a point at hundred volt to a point at 120 volt​

Answer 1

Answer:

work done = q(v2 - v1)

= 0.004×(120 -100)

=0.004×20

=0.08

Answer 2

Answer:

IF The charge in Mega Coulomb (MC) 80 Mega Joule (MJ) OR If the charge is in Mili coulomb (mc) 0.08 J

Step-by-step explanation:

Q = 4MC= 4 × 10^6C. ( as 1MC- 10^6C)

V1= 100V

V2 = 120V

So, V = V2- V1

V = 120-100

V = 20V.

We know , Work done = Q × V

= 4 × 10^6 × 20

= 80 × 10^6 Joule.

= 80MJ

OR

IF THE CHARGE IS IN Mili coulomb (mc)Then Q = 0.004C.

V1= 100V

V2 = 120V

So, V = V2- V1

V = 120-100

V = 20V.

We know , Work done = Q × V

= 0.004 × 20

= 0.08Joule.
