Question

plzzz explain this question

Answer 1

I Think It's A and B Because

If You Will Look The Formula of Time Period It's

T = $\huge \red{T = 2 \pi \sqrt{\frac{l}{g}}}$

So It's Directly Proportional To The Square Root of The Length Of The Pendulum and Inversely Proportional To The Square Root of The acceleration due to gravity!!

Mass Shape Size Material of BOB Doesn't Affect Time!!

and Amplitude Also Doesn't Affect The Time Period

Answer 2

HERE COMES THE ANS:-

IT'LL BE C AND D BECAUSE IT'S INDEPENDENT OF AMPLITUDE AND INDEPENDENT OF MASS ❤☺❗
