QUESTION 14
Two point charges +2.0μC and −3.0μC are separated by 0.40m. What is the magnitude and nature of the electrostatic force? (A)0.337N, attractive (B)0.337N, repulsive (C)3.37N, attractive (D)3.37N, repulsive WORKED SOLUTION
Answer A
1 markWorked solution
F=k∣Qq∣/r2=(8.99×109)(2.0×10−6)(3.0×10−6)/(0.40)2=0.337N. Opposite charges attract. Select the correct option.
