[CBSE PMT 1998; AIIMS 2001; AFMC 2002; CPMT 2004]
Options:
A) 1.47 Hz
B) 0.36 Hz
C) 0.73 Hz
D) 2.94 Hz
Show Answer
Answer:
Correct Answer: A
Solution:
Time required for a point to move from maximum displacement to zero displacement is $ t=\frac{T}{4}=\frac{1}{4n} $
Therefore $ n=\frac{1}{4t}=\frac{1}{4\times 0.170}=1.47,Hz $
