Question

A point charge q1 = is located at the center of a thick conducting spherical shell of inner radius a = 2.2 cm and outer radius b = 4.5 cm, The conducting spherical shell has a net charge of q2 = 2.6 μC. 1)What is Ex(P), the value of the x-component of the electric field at point P, located a distance 8.8 cm along the x-axis from q1?

Answer 1

Answer:

Ex(P) = -3.602 x 10^6 N/C

Explanation:

• given q1 = -5.7μC

• q2 = 2.6 μC = the net charge on the conducting shell

• inner radius of conducting shell = a = 2.2 cm =0.022m

• outer radius of conducting shell = b = 4.5 cm = 0.045m

1) To get Ex(P), the value of the x-component of the electric field at point P, located a distance 8.8 cm along the x-axis from q1 ;

Ex(P) = k(q1+q2)/r^2

= 9 x 10^9 (-5.7 + 2.6) x 10^-6 /0.088^2

Ex(P) = -27.9 x 10^3/ 0.007744

Ex(P) = -3.602 x 10^6 N/C
