Coulomb's Law and Electric Field Quiz

$F = \frac{Q1 \cdot Q2}{4\pi\epsilon_0 R_{12}^2}$ (correct)

$F = \frac{Q1 + Q2}{R_{12}}$

$F = \frac{Q1 \cdot Q2}{R_{12}}$

$F = \frac{Q1 + Q2}{4\pi\epsilon_0 R_{12}^2}$

The magnitude of the force between Q1 and Q2

The position vector of Q2 relative to Q1

The displacement vector of Q2 relative to Q1

The unit vector in the direction of the line segment from Q1 to Q2 (correct)

$R12 = 1\hat{a}_x + 2\hat{a}_y + 3\hat{a}_z$

$R12 = 1\hat{a}_x - 2\hat{a}_y + 2\hat{a}_z$

$R12 = 2\hat{a}_x - 2\hat{a}_y + 2\hat{a}_z$

$R12 = 2\hat{a}_x + 0\hat{a}_y + 5\hat{a}_z$ (correct)
