Question

The equipotential surfaces in theneighborhood of a positive point charge are spheres. Which sphereis associated with the higher electric potential? the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct the larger one the smaller one they are associated with the samepotential Correct Part B the larger one the smaller one they are associated with the samepotential Correct

Explanation / Answer

potential v = kq/r     where r is distance from the positivecharge so smaller one has higher potential given charge q = 2.60c         v =kq(1/r1 - 1/r2) where r1 = 11.1m r2 =12.6m and k = 9*109 plug in values and do caliculations then work done W = ve where e = 1.6*10-19c plug values and docaliculations    then    W/1.6*10-19c = ----------ev plug in values and do caliculations then work done W = ve where e = 1.6*10-19c plug values and docaliculations    then    W/1.6*10-19c = ----------ev
