Electric Charges and Fields · Charge and Coulomb's law

Two point charges q1=3 μq_1 = 3\ \muC and q2=−4 μq_2 = -4\ \muC are placed at points (2i^+3j^+3k^)(2\hat i + 3\hat j + 3\hat k) and (i^+j^+k^)(\hat i + \hat j + \hat k) respectively. Force on charge q2q_2 is N. (Take 14πϵ0=9×109 SI Units)\left(\text{Take } \dfrac{1}{4\pi\epsilon_0} = 9\times10^{9}\ \text{SI Units}\right)
  1. (1)(12i^+24j^+24k^)×10−3(12\hat i + 24\hat j + 24\hat k)\times10^{-3}
  2. (2)(4i^+8j^+8k^)×10−3(4\hat i + 8\hat j + 8\hat k)\times10^{-3}
  3. (3)(3i^+6j^+6k^)×10−3(3\hat i + 6\hat j + 6\hat k)\times10^{-3}
  4. (4)(−4i^−8j^−8k^)×10−3(-4\hat i - 8\hat j - 8\hat k)\times10^{-3}
