List of top Physics Questions on Dual nature of radiation and matter asked in BITSAT

Young's double slit experiment is performed in a medium of refractive index \( 1.33 \). The maximum intensity is \( I_0 \). The intensity at a point on the screen where the path difference between the light coming out from slits is \( \lambda/4 \), is:
A dust particle of mass \(4 \times 10^{-12} \, {mg}\) is suspended in air under the influence of an electric field of 50 N/C directed vertically upwards. How many electrons were removed from the neutral dust particle? [Take, \(g = 10 \, {m/s}^2\)]
A particle of mass \( m \) is projected with a velocity \( u \) making an angle of \( 30^\circ \) with the horizontal. The magnitude of angular momentum of the projectile about the point of projection when the particle is at its maximum height \( h \) is:
