Gravitational acceleration at a place using a second pendulum is calculated. The reading comes out to be 9.86 m/s2, 9.72 m/s2, 9.64 m/s2, and 9.98 m/s2. Calculate the range where gravitational acceleration lies in that place.
1
between 9.69 m/s2 and 9.93 m/s2
2
between 9.69 m/s2 and 9.81 m/s2
3
between 9.81 m/s2 and 9.93 m/s2
4
between 9.86 m/s2 and 9.98 m/s2
