White light passing through a prism splits into its constituent colors because:

Two resistors of 6 Ω and 3 Ω are connected in parallel. What is the equivalent resistance?

A solid sphere and a solid cylinder of same mass M and same radius R roll down an inclined plane from rest. The ratio of their accelerations (a_sphere/a_cylinder) is:

The drift speed of electrons in a copper wire of diameter 2 mm carrying a current of 2 A is approximately: (Number density of free electrons in copper n = 8.5 × 10²⁸ m⁻³, e = 1.6 × 10⁻¹⁹ C)

Two planets have masses M and M and radii R and 4R respectively. If the escape velocities are v₁ and v₂ respectively, then v₁/v₂ is:

A body of mass m moves in a circle of radius r with uniform speed v. The centripetal force is:

In an LCR series circuit, L = 100 mH, C = 100 μF, and R = 100 Ω. The resonant frequency of the circuit is approximately: (π = 3.14)

Two identical black body plates P and Q at temperatures T_P and T_Q (T_Q < T_P). Power per unit area from P to Q is W₀. Two more identical plates inserted between P and Q. Heat transfer only between adjacent plates. In steady state, power per unit area from P to Q is W_S. Ratio W₀/W_S is:
