G1 Physics · Accepted Answer

Step 1: A stationary charge experiences magnetic force F⃗_B = q(v⃗ × B⃗). Step 2: Since the charge is stationary, v⃗ = 0; its force is zero regardless of the magnetic fields produced by the two bar magnets. Step 3: Therefore F⃗_B = 0. Final answer: option A (zero). Final answer: (A) zero.
