Question

The figure shows a very large nonconducting sheet that has a uniform surface charge density *σ* = -3.10 μC/m^{2}; it also shows a particle of charge *Q* = 6.20 μC, at distance *d* from the sheet. Both are fixed in place. If *d* = 24.0 cm, at what **(a)**positive and **(b)** negative coordinate on the *x* axis (other than infinity) is the net electric field of the sheet and particle zero? **(c)** If *d* = 95.0 cm, at what coordinate is ?
