Answer:
A) is repelled by the sphere
Explanation:
- When a piece of plastic is rubbed with a wooden cloth, it sinks negatively
- Let it change Q. So it is now allowed to touch the neutral zone. Therefore, there is a difference in the surface capacity of the two bodies, so that charge transfer takes place
- Some of its negative charge is transferred to the metal sphere, now both the rod and the sphere are negatively charged and the same chargers as we know are repelled by each other.
- so correct answer is A) is repelled by sphere
D. Rutherford found that the atom consists of a small positively charged nucleus.
Explanation:
KE = KE
½ mv² = ½ mv²
½ (1.88 g) v² = ½ (230.5 g) (58.5 m/s)²
v = 648 m/s
