If mass is written as m = k cᴾ G⁻¹⁄² h¹⁄² then the value of P will be: (Constants have their usual meaning with k a dimensionless constant)
A block of mass m is placed on a surface having vertical crosssection given by y = x²/4. If coefficient of friction is 0.5, the maximum height above the ground at which block can be placed without slipping is:
Escape velocity of a body from earth is 11.2 km/s. If the radius of a planet be one-third the radius of earth and mass be one-sixth that of earth, the escape velocity from the planet is :
A particle of charge ‘−q’ and mass ‘m’ moves in a circle of radius ‘r’ around an infinitely long line charge of linear charge density +λ. Then time period will be given as : (Consider k as Coulomb's constant)
When a potential difference V is applied across a wire of resistance R, it dissipates energy at a rate W. If the wire is cut into two halves and these halves are connected mutually parallel across the same supply, the energy dissipation rate will become:
An alternating voltage V(t) = 220 sin 100 πt volt is applied to a purely resistive load of 50 Ω. The time taken for the current to rise from half of the peak value to the peak value is:
If the total energy transferred to a surface in time t is 6.48×10⁵ J, then the magnitude of the total momentum delivered to this surface for complete absorption will be:
A beam of unpolarised light of intensity I₀ is passed through a polaroid A and then through another polaroid B which is oriented so that its principal plane makes an angle of 45° relative to that of A. The intensity of emergent light is:
