Options
- A(\mathrm{A} \rightarrow \mathrm{PQR}, \mathrm{B} \rightarrow \mathrm{PR}, \mathrm{C} \rightarrow \mathrm{PQ}, \mathrm{D} \rightarrow \mathrm{PQ})
- B(\mathrm{A} \rightarrow \mathrm{R}, \mathrm{B} \rightarrow \mathrm{R}, \mathrm{C} \rightarrow \mathrm{Q}, \mathrm{D} \rightarrow \mathrm{RS})
- C(\mathrm{A} \rightarrow \mathrm{PQR}, \mathrm{B} \rightarrow \mathrm{PQR}, \mathrm{C} \rightarrow \mathrm{PQ}, \mathrm{D} \rightarrow \mathrm{RS})
- D(\mathrm{A} \rightarrow \mathrm{PQR}, \mathrm{B} \rightarrow \mathrm{P}, \mathrm{C} \rightarrow \mathrm{PQ}, \mathrm{D} \rightarrow \mathrm{RS})
Correct answer
B. (\mathrm{A} \rightarrow \mathrm{R}, \mathrm{B} \rightarrow \mathrm{R}, \mathrm{C} \rightarrow \mathrm{Q}, \mathrm{D} \rightarrow \mathrm{RS})
Step-by-step solution
- (A) Force between a proton and a proton inside the nucleus (\rightarrow(\mathrm{R})) Strong force: The force between two protons in the nucleus is primarily the strong nuclear force, which is responsible for holding the nucleus together despite the electrostatic repulsion between the positively charged protons.
- (B) Force between a proton and a neutron inside the nucleus (\rightarrow(\mathrm{R})) Strong force:
The force between a proton and a neutron is also the strong nuclear force, which is the dominant force acting within the nucleus.
- (C) Force on an electron in an atom
(\rightarrow) (Q) Electrostatic force:
The force acting on an electron in an atom due to the nucleus (which is positively charged) is an electrostatic force (Coulomb's law).
- (D) Conservative force (\rightarrow(\mathrm{R})) and (S):
A conservative force can refer to both the electrostatic force and the gravitational force, but in the context of nuclear interactions, the primary focus is on the strong and weak forces. Since both the strong force and weak force are fundamental forces, this option can be interpreted to include both.
Thus, the correct matching is:
(A \rightarrow R, B \rightarrow R, C \rightarrow Q, D \rightarrow R S .)
