Question

PrimePay's HR Advisory Advanced includes ____ employee training courses.

a) No
b) 5
c) 10
d) 20

Answer 1

The answer is 20 field lines.

Step-by-step explanation:

The answer is d) 20 field lines. The number of electric-field lines is directly proportional to the magnitude of the charge. Since the charge is four times greater (+20 nC compared to +5 nC), the number of field lines would also be four times greater. Therefore, there should be 20 electric-field lines coming out of a +20 nC charge.
