Two copper spheres are placed 0.04 m apart on a horizontal surface. The charge of sphere A is -4 microCoulombs, while sphere B has a charge of +2.0 microCoulombs. Which of the following statements is correct? (1 microCoulomb = 1 x 10-6 Coulombs)
Group of answer choices:
1. Sphere A will feel a smaller electric force compared to sphere B.
2. The magnitude of the force exerted on sphere B will be 45 N and the force will be attractive.
3. The magnitude of the force exerted on sphere A will be double the force exerted on sphere B.
4. Both spheres will feel an attractive force towards each other. The magnitude of the force will be 4.5 x 10^13 N.
