Question

Match List-I with List-II 

List-I	Concept	List-II	Type / Relation
A	Torque	II	Rotational Motion
B	Force	III	Linear Motion
C	Rocket	IV	Variable Mass
D	Parallel LCR Circuit	I	Rejector Circuit

• A. A-II, B-III, C-IV, D-I
• B. A-III, B-IV, C-I, D-II
• C. A-I, B-II, C-III, D-IV
• D. A-II, B-IV, C-I, D-III

Hint:

Parallel resonant LCR circuit is called a rejector circuit because it offers high impedance at resonance.

Answer 1

The Correct Option is A

Concept:
This question matches physical quantities or systems with their related applications or motion.

Step 1: Torque.
Torque is the turning effect of force and is related to rotational motion. \[ A\rightarrow II \]

Step 2: Force.
Force is directly related to linear motion through Newton's second law. \[ F=ma \] So, \[ B\rightarrow III \]

Step 3: Rocket.
A rocket is a variable mass system because it continuously ejects fuel. \[ C\rightarrow IV \]

Step 4: Parallel LCR circuit.
A parallel LCR circuit at resonance is known as a rejector circuit. \[ D\rightarrow I \] Therefore: \[ A-II,\ B-III,\ C-IV,\ D-I \] \[ \therefore \text{Correct Answer is (A)} \]
