QNEET-2022-Ph-538: NEET 2022 Physics - Class 11 NEET-2022-Ph-538 Solution: Match List-I with List-II List-I (x-y graphs) List-II…
Match List-I with List-II List-I (x-y graphs) List-II (Situations) (a) (i) Total mechanical energy is conserved (b) (ii) Bob of a pendulum is oscillating under negligible air friction (c) (iii) Restoring force of a spring (d) (iv) Bob of a pendulum is oscillating along with air friction Choose the correct answer from the options given below
Multiple Choice Options
- A (a) - (iii), (b) - (ii), (c) - (i), (d) - (iv)
- B (a) - (iv), (b) - (ii), (c) - (iii), (d) - (i)
- C (a) - (iv), (b) - (iii), (c) - (ii), (d) - (i)
- D (a) - (i), (b) - (iv), (c) - (iii), (d) - (ii)
Step-by-Step Verified Solution
(a)
Amplitude of oscillation is continuously decreasing. It means bob of pendulum oscillate with air friction.
(b)
F = _ k x (restoring force of a spring)
(c)
Amplitude of oscillation is remains same. It means bob of pendulum is oscillating under negligible air resistance.
(d)
P . E . = 1 2 k x 2 , K . E . = 1 2 m _ 2 A 2 _ 1 2 k x 2
T . E . = 1 2 m _ 2 A 2 = constant
