Question

a) increase
b) remain same
c) decrease
d) first increase and then decrease

Answer 1

Time period is = 2π√l/g
It means the time period is independent of mass so time period will not be affected whether we use metal or wooden bob.

So answer is b) remain same



Plzz mark it brainliest if you like!!!!

Answer 2

Answer is B.

The time period will remain same because the distance of the centre of mass of the Bob will remain same when we use a wooden Bob instead of a metal one.
