Answer: The time period will get increased by a factor of 2
Step-by-step explanation:
As we know,
The time period of a simple pendulum is 2π√(m/g)
If the mass is increased by a factor of 4, so let us assume the original mass as m.
the new mass would be 4m.
the original time period will be T=2π√(m/g)
the new time period will be T' = 2π√(4m/g) = 2T
Hence, the time period gets increased by a factor of 2.
