Moving a charge from point A, where the potential is 370V , to point B, where the potential is 190V , takes 4.1×10−4J of work.
Part A
What is the value of the charge?
To find the value of the charge, we can use the formula for the work done while moving a charge between two points:
Work = Charge x Potential Difference
We are given the work done (W) as 4.1×10−4 J, the potential at point A (VA) as 370 V, and the potential at point B (VB) as 190 V.
We can rearrange the formula to solve for the charge (Q):
Q = W / (VB - VA)
Substituting the given values:
Q = 4.1×10−4 J / (190 V - 370 V)
Q = 4.1×10−4 J / (-180 V)
Q = -2.28×10−6 C
Therefore, the value of the charge is -2.28×10−6 Coulombs.
