You did not use the information about torque though

[empty moon]

Bro we need to find normal reaction

That's a force so why calculate torque

[hybrid isle]

To relate with mg?

I think I get it lemme try I figured it out

@hybrid isle

@hybrid isle what's the answer?

That Normal reaction is taken on the centre of mass a semi circular ring...i.e 2R/π from centre

Since we are considering half ring...i took mg/2
