My attempt

It seems to be 1

[sour falcon]

anyone??

[azure owl]

Which fiitjee are you from

[frail orbit]

Nice
I'm also curious to know about this

[sour falcon]

south delhi

[sour falcon]

know about what ?

the answer ?

[gilded spoke]

Is it 1? @sour falcon

[sour falcon]

Its sec sq theta

1 hota toh yeh doubt idhar aata hu nahi 💀

I saw online but the soln isn't convincing

[azure owl]

Initially it is in equilibrium

So equate them and find the tension

At b it is not in equilibrium

There is no centripetal acceleration because v is zero

[frail orbit]

I also saw solutions online but not convincing ,
Like what's the mistake in your steps ...that's the topic of curiosity ..

[azure owl]

Let me send a solution

Centripetal acceleration in second case is zero so all forces along the line of the radius add up to zero

[frail orbit]

May be because ,
Taking the component of tension force will not be able to perform swing

[sour falcon]

is it somewhere related to circular and rotational motion

i hvnt studied that yet

[rustic tiger]

yes but yaha par he's just saying ki it isn't in equilibrium vertically but is radially (towards centre)

[azure owl]

Kinda

Centripetal acceleration is basically acceleration towards the centre

We dont need to use that to do the math but we need to know that the force along the radius is zero

[sonic cove]

we good?
