\(T=2 \pi \sqrt{\frac{l}{g}}\) or \(T \propto \sqrt{\frac{l}{g}}\)
when the elevator is accelerating downwards, the net gravitational acceleration is \((g-a),\) so, the time period when elevation is accelerating downwards, is greatest.
$x\left( t \right) = A\,\sin \,\left( {at + \delta } \right)$
$y\left( t \right) = B\,\sin \,\left( {bt} \right)$
તો નીચેનામાંથી શું સાચું પડશે?
