A point on a wave completes one cycle every 5 seconds. The frequency of this wave is 1/5 seconds. Question 2 options:
True
False

In one experiment the electric field is measured for points at distances r from a uniform line of charge that has charge per unit length λ and length l, where l≫r. in a second experiment the electric field is measured for points at distances r from the center of a uniformly charged insulating sphere that has volume charge density ρ and radius r
