Physics U5 L12 Other Forces Unit Test
1. D, the apple and Earth
2. A, The objects will feel a greater force when they get closer to each other.
3. B, The force weakens by a factor of 4.
4. A, Gravitational force is negative because it is attractive.
5. B, the product of the masses of the two objects divided by the square of the distance between them
6. D, The electrostatic force remains attractive, and the magnitude does not change.
7. C, when q is doubled and r is doubled
8. C, Only negative because of the formula, indicating attractive forces.
9. D, 9.3 C each
10. C, 38.7 kg
11. B, 1.859 × 10−⁹ kg
12. C, The value of the electric field is 0 V/m. The positive charge would not feel any force and would stay put.
13. D, decreasing the magnitude of the charges of the particles
14. D, G + m₁m₂ + d + FG -
15. A, It is always attractive.
16. B, It indicates a repulsive force between two like charges.
17. C, Gravity is always an attractive force, but the electrostatic force can be either attractive or repulsive.
18. D, 2.64 × 10⁶ m
19. A, The stationary particle and the particle that is free to move both have the same charge.
20. *Short answer question. You have to do this yourself, sorry!*
