Question

calculate the work done in moving a charge of 5 column from a point at 20 volt to another at 30 volt​

Answer 1

Answer:

v=30-20=10v

Q=5c

v=w/Q

w=vQ

10×5=50J

Answer 2

work done(W)=charge(Q) x potential difference(v)                                                                                                                                                                      V = potential differnce between the two points which is 240-210=30

   

 Q=5C

  

 W=QV,   5 x 30=150Juoles
