Vedclass · Answer

(A) Given: Charge $q_1 = 2 	imes 10^{-7}  C$ Charge $q_2 = 3 	imes 10^{-7}  C$ Distance $r = 30  cm = 0.3  m$ Coulomb's constant $k = 9 	imes 10^9  N \cdot m^2/C^2$ According to Coulomb's Law, the force $F$ is given by: $F = k \frac{q_1 q_2}{r^2}$ Substituting the values: $F = (9 	imes 10^9) 	imes \frac{(2 	imes 10^{-7}) 	imes (3 	imes 10^{-7})}{(0.3)^2}$ $F = \frac{9 	imes 10^9 	imes 6 	imes 10^{-14}}{0.09}$ $F = \frac{54 	imes 10^{-5}}{0.09}$ $F = 600 	imes 10^{-5}  N = 6 	imes 10^{-3}  N$ Therefore, the correct option is $A$.
