Two light beams of intensities in the ratio of 9:4 are allowed to interfere. The ratio of the intensity of maxima and minima will be:
Magnetic field at the centre of a circular coil of radius \( r \), through which a current \( I \) flows is:
A bob of mass \( m \) is suspended by a light string of length \( L \). It is imparted a minimum horizontal velocity at the lowest point A such that it just completes half a circle, reaching the topmost position B. The ratio of kinetic energies \(\left(\frac{K.E.}{K.E.}\right)_A \), \(\text{to}\), \(\left(\frac{K.E.}{K.E.}\right)_B\) is:
Spherical insulating ball and a spherical metallic ball of same size and mass are dropped from the same height. Choose the correct statement out of the following (Assume negligible air friction):
Two cells of the same emf but different internal resistances \( r_1 \) and \( r_2 \) are connected in series with a resistance \( R \). The value of resistance \( R \), for which the potential difference across the second cell is zero, is:
A small ball of mass \( M \) and density \( \rho \) is dropped in a viscous liquid of density \( \rho_0 \). After some time, the ball falls with a constant velocity. What is the viscous force on the ball?
Under the same load, wire A having length 5.0 m and cross-section \( 2.5 \times 10^{-5} \, \text{m}^2 \) stretches uniformly by the same amount as another wire B of length 6.0 m and a cross-section \( 3.0 \times 10^{-5} \, \text{m}^2 \) stretches. The ratio of the Young's modulus of wire A to that of wire B will be:
