Q48 / 214 · NTA Abhyas (NEET) 2020 · Physics · Oscillations

In an experiment, to find the loss of energy with respect to time in case of swinging simple pendulum, the graph between (amplitude)² and time is

Correct answer
A
B
C
D

Solution

E = \frac{1}{2} K a^{2}

E = \frac{1}{2} m ω^{2} a^{2}

So

a^{2} t = c o n s t a n t

Hence, the correct answer is option: 'A'.
