A wall clock regulated by a seconds pendulum goes slow by 20 second per day. How many oscillation are performed by the faulty pendulum per day ?

A

43000

B

43100

C

43200

D

43190

Text Solution

Verified by Experts

The correct Answer is:
D
The number of oscillations performed by the correct seconds pendulum per day
`(N)=(24xx60xx60)/(2)=43,200`
The faulty pendulum performs `(20)/(2)=10` oscillations less than the required number per day.
`therefore` Actual no. of oscillation =43,00-10=43,190
