Question

What is the magnitude of a point charge whose electric field 50 cm away has magnitude 2 N/C?
Options
A 3.76x10-11 C
B 4.05x10-11 C
C 5.56x10-11 C
Correct Answer
D 2.00x10-11 C
Correct Answer

Option C is the correct answer.

Detailed Explanation

E = kq/r2 => q = E r2/k = (2)(0.5)2/(9x109) = (2)(0.25)/9x109 = 0.5/9x109 = 5.56x10-11 C.

Hint

E = kq/r2 => q = E r2/k = (2)(0.5)2/(9x109) = (2)(0.25)/9x109 = 0.5/9x109 = 5.56x10-11 C.
