The origin of an x axis is placed at the center of a nonconducting solid sphere of radius r that carries a charge +qsphere distributed uniformly throughout its volume. a particle that carries an unknown charge qpart is located on the x axis at x=+2r. the magnitude of the electric field due to the sphere-particle combination is zero at x=+r/4 on the xaxis.
part a
what is qpart in terms of qsphere?
express your answer in terms of qsphere.
qpart =

part b
at what other locations on the x axis is the electric field zero?
