Score for PP H6 PHYS 360-Practice Page #6 NAME Due: Tuesday, September 11, 2018 ot 2.00 AM Bring it to class, done. It will be collected at the start Consider the three point-charges illustrated here. They are small amounts of charge, notice the "nC," which stands for nano-Coulomb. Look carefully at their locations along the x-axis. Each of the charges produces its own electric field. q+3.0nC Q2=-6.0 nC qs = +3.0 nC 0 10 x (cm) 1. Calculate the magnitude of the electric field Ei produced by q1 at the point with coordinate x 5.0 cm. In what direction is the electric field E, atx-5.0cm, left or right? 2. Calculate the magnitude of the electric field E2 produced by q2 at the point with coordinate x = 5.0 cm. In what direction is the electric field E2 at x 5.0 cm, left or right?

Explanation / Answer

Electric field due to q1 at x= 5 cm

E= kq/r^2= 9*10^9 *3*10^-9/0.02^2= 67500 N/C

Directed to the right

==========

Electeic field due to q2 at x= 5cm

E= 9*10°9*6*10^-9/0.03^2 = 60000 N/C

Directed to the right

=========

Comment in case any doubt.. good luck
