Question

solve this fast Anthe 2018 solution

Answer 1

it will be complete in 4s

Answer 2

Answer: 14 s

Explanation:

The time period of a pendulum is given by time taken to complete one oscillation.

When pendulum starts from extreme position A and goes to B via C and returns back to A, this is said to be one oscillation.

The pendulum takes 3 s to complete three-fourth of the oscillation.

Let the time period of the pendulum be T

Then,

$\frac{3T}{4}= 3 s$

$\Rightarrow T = 4 s$

Hence, the time period of the pendulum is 4 s. It means time taken to complete 1 oscillation is 4 s

So, time taken to complete 3.5 oscillations would be = 3.5 × 4 s = 14 s
