Response:

the formula for period is T=2π√(l/g)

in order to have a period of 1 sec... on earth

1sec=2π√(l//9.8m/s²)

(1/2π)² x 9.8m/s²=l=.248m if taken to a different planet with same length a= lets say 10m/s²

T=2π√(.248m/10m/s²)

T=.99sec

period is smaller cuz the pendulum accelerates faster.

Response:

we know that time period of a simple pendulum is

from here time period is inversly proportional to the gravity.

so, if gravity increases time period decreases.

Therfore i think the time period will be less than 1 sec.
