In a gultar, two strings \(A\) and \(B\) made of same materlal are slightly out of tune and produce beats of frequency \(6\, Hz\). When tension in \(B\) is slightly decreased, the beat frequency increases to \(7 \,Hz\). If the frequency of \(A\) is \(530\, Hz ,\) the orlginal frequency of \(B\) will be \(.........Hz\)
- A \(537\)
- B \(523\)

- A balloon is made of a material of surface tension \(S\) and its inflation outlet (from where gas is filled in it) has small area \(A\). It is filled with a gas of density \(\rho\) and takes a spherical shape of radius \(R\). When the gas is allowed to flow freely out of it, its radius changes from \(R\) to 0 (zero) in time \(T\). If the speed \(\eta(r)\) of gas coming out of the balloon depends on \(r\) as \(r^\alpha\) and \(T \propto S^\alpha A^\beta \rho^\gamma R^\delta\) thenNEET 2025 Hard
