If now both the blocks are pushed to the left, so that the spring is compressed at a distance \(d\). The amplitude of oscillation of block of mass \(m_1\) after the system is released, is
A coil in the shape of an equilateral triangle of side \(l\) is suspended between the pole pieces of a permanent magnet such that \(\mathbf{B}\) is in the plane of the coil. If due to current \(i\) in the triangle, a torque \(\tau\) acts on it. The side \(l\) of the triangle is
A thin film of soap solution (\(\mu_s = 1.4\)) lies on the top of a glass plate (\(\mu_g = 1.5\)). When incident light is almost normal to the plate, two adjacent reflection maxima are observed at two wavelengths 420 nm and 630 nm. The minimum thickness of the soap solution is
