Answer:
Similarities:
Both are based on developments in quantum mechanics, both involve a centrally located mass of protons and neutrons (nucleus)
Differences:
nucleus: Electrons distinct and follow a definite orbit around nucleus
Cloud: No definite orbit for electrons around nucleus, only probability distributions of where electron is likely to be.
Answer:
True.
Explanation:
If the sum of the external forces on an object is zero, then the sum of the external torques on it must also be zero.
The net external force and the net external torque acting on the object have to be zero for an object to be in mechanical equilibrium.
Hence, the given statement is true.
