Question

9. If 100 J of work must be done to move electric charge equal to 4C from a place where potential is –10 V to
another place where potential is V volt, find the value of V.
a) 15 V b) 307
c)45v
d) GOV
10. If​

Answer 1

Answer:

a)15 V ...is Ur answer mate

Answer 2

Given work done = 100J

charge q = 4C

from potential V¹= -10 Volts to V²= V Volts

so,

W=q△V

W=q(V²−V¹)

W=4[V²−(−10)]

$\frac{4}{100} = {v}^{2} + 10$

V²=15volts
