What is the strength of the electric field 0.020 m from a 12 uc charge? 5.4 x 106 N/C

O 2.7 x 108 N/C

O 5.4 x 1012 N/C

O 2.7 x 1014 N/C

Option B is correct.

Explanation:

Given the charge, Q = 12uC

Now convert the uC into C = 5*10^-6 C

Given, d = 0.020 m

Now use the below formula:

E = K*Q/d^2

Now insert all the values in the above formula and then solve.

E = (9 ×10^9) × (12×10^-6) / (0.020)^2

E  = 2.7 ×10^8 N/C

Therefore option B is correct.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
