Given a charge q, current I and permeability of vacuum μ₀. Which of the following quantity has the dimension of momentum?
The moment of inertia of a circular ring of mass M and diameter r about a tangential axis lying in the plane of the ring is :
Two water drops each of radius ‘r’ coalesce to form a bigger drop. If ‘T’ is the surface tension, the surface energy released in this process is :
Identify the characteristics of an adiabatic process in a monoatomic gas.
An electron with mass ‘m’ with an initial velocity (t = 0) v⃗ = v₀ î (v₀ > 0) enters a magnetic field B⃗ = B₀ ĵ. If the initial de-Broglie wavelength at t = 0 is λ₀ then its value after time ‘t’ would be :
A sinusoidal wave of wavelength 7.5 cm travels a distance of 1.2 cm along the x-direction in 0.3 sec. The crest P is at x = 0 at t = 0 sec and maximum displacement of the wave is 2 cm. Which equation correctly represents this wave ?
If μ₀ and ε₀ are the permeability and permittivity of free space, respectively, then the dimension of (1/μ₀ε₀) is :
Two identical objects are placed in front of convex mirror and concave mirror having same radii of curvature of 12 cm, at same distance of 18 cm from the respective mirrors. The ratio of sizes of the images formed by convex mirror and by concave mirror is :
