1. NEET 2026EasyKepler's Laws
   Q1

   In a solar system, the time-period of revolution of a planet tracing a circular orbit of radius $R$ is proportional to:

   • A$R^{1/2}$
   • B$R^{3/2}$
   • C$R^2$
   • D$R^3$

   Show answer & solution

   Correct answer: (B)

   Kepler's third law: $T^2\propto R^3$
   
   $\Rightarrow T\propto R^{3/2}$.
2. NEET 2026EasyOrbital & Escape Velocity, Satellite Motion
   Q2

   Two planets $P_1$ and $P_2$ with equal mass have radii $R_1$ and $R_2$, respectively, where $R_2=\frac{R_1}{2}$. The
   
   escape speeds of $P_1$ and $P_2$ are $v_1$ and $v_2$,
   
   respectively. Then $\frac{v_2}{v_1}$ is:

   • A$\frac{1}{\sqrt{2}}$
   • B1
   • C$\sqrt{2}$
   • D2

   Show answer & solution

   Correct answer: (C)

   Escape speed $v_e=\sqrt{\frac{2GM}{R}}$. Mass is same.
   
   $\frac{v_2}{v_1}=\sqrt{\frac{R_1}{R_2}}=\sqrt{\frac{R_1}{R_1/2}}=\sqrt{2}$.
3. NEET 2026MediumGravitational Potential & Potential Energy
   Q3

   The amount of work done to raise a mass 'm' from the surface of the Earth to a height equal to the radius of the Earth 'R' will be

   • A$2mgR$
   • B$mg\frac{R}{4}$
   • C$mgR$
   • D$mg\frac{R}{2}$

   Show answer & solution

   Correct answer: (D)

   Work done = change in potential energy =
   
   $$U_2-U_1=\left(-\frac{GMm}{2R}\right)-\left(-\frac{GMm}{R}\right)=\frac{GMm}{2R}=\frac{mgR}{2}$$
   
   (since $GM=g{R}^2$).
