Question

Answer True or False to each case. Coulomb's law states that the force between static charges Q1 and Q2 True is proportional to 1/r2 Truemay be attractive or repulsive. Falseis a force of attraction. True is K Q1Q2/r where K is a universal constant. | Faise is proportional to 1/r. Submit Answer Incorrect. Tries 5/6 Previous Tries

Answer 1

According to Coulomb's law
force = (k*q1*q2)/r^2

1)
so,
force is proportional to 1/r^2
True

2)
if both the charge of same polarity then force will be repulsive
and if charge is of same polarity then force will be attractive
so, force may be attractive or repulsive
True

3)
force may be attractive or repulsive
False

4)
force is given by = (k*q1*q2)/r^2
False

5)
force is proportional to 1/r^2
False
