Question

A uniformly charged disk with radius R = 25.0 cmand uniform charge density ? = 7.40 ✕ 10−3 C/m2 lies in the xy-plane, with its center at the origin. What is the electric field (in MN/C) due to the charged disk at the following locations? (a)z = 5.00 cm (b)z = 10.0 cm(z)= 50.0 cm(d)z = 200 cm

Expert Solution
Step 1

Ez = k(d)2π[ 1- (z / √ z2 +R2)] 

R= 25cm = 0.25m 

d = 7.4× 10-3 C/m2
