Considering 
; describe in symbolic
form, the work required to move a charge "Q" across (a) an
equipotential line and (b) an electric field line. Explain your
results.
Homework Answers
The equation which relates workdone , and potential difference and charge is
W= del V Q
in equipotential line, the potential difference is constant (0)
so work required to move charge W = 0
(b)
the relation between electric field and force is
F = Eq
work required to move charge Q in an electric field is
here si = initial position of charge and sf is final position of charge.

Help me please to answer on these questions. Thank you! 1. Is work required to move an electric charge along a line of equipotential? Explain. (Think about the strength of the force along these lines and which way it is pointing.) 2. Points P and Q are on the same equipotential lines in an electric field and points R and S are on a higher equipotential line. Compare the work done by the electric field when an electric particle with...

Work done can also be determined by considering movement across equipotentials. This can be written as: Vn is the electric potential at point P This tells us that the work done by you is dependent only on the magnitude and type (+ or -) of the electric charge you are trying to move, and the difference in electric potential from the ending point to the starting point. Both of these equations could yield positive or...

Calculate the amount of work that would be required to move a small positive test charge q0q0 slowly from r=2Rr=2R to r=7Rr=7R. Assume that the presence of q0q0 has no effect on how the charge qq is distributed over the sphere. Express your answer in terms of the electric constant ϵ0ϵ0epsilon_0 and some or all of the variables q, q0, and R.
