I do not know answer of this question

Answer 2

we know that... formula of time period is...

➡️t=2π√l/g

when the girl stands up the centre of mass will shift upwards and effective length will decrease ... hence time period will decrease...

since frequency is reciprocal of time period... it will increase...
