Sample questions

1. 1.A point mass outside a uniform spherical shell experiences a force as if:
   • A.the shell mass is zero
   • B.the entire shell mass is at its centre
   • C.the mass is on the near surface
   • D.only half the mass acts
2. 2.A planet has the same density as the earth but twice its radius. The acceleration due to gravity on its surface (g proportional to rho R) is:
   • A.2 g
   • B.g/2
   • C.4 g
   • D.g
3. 3.Which statements are correct? (1) g decreases by (1 - 2h/RE) at small height h; (2) g decreases by (1 - d/RE) at depth d; (3) g is independent of the body's mass.
   • A.1, 2 and 3
   • B.1 and 2 only
   • C.1 and 3 only
   • D.2 and 3 only
4. 4.![kepler_law_of_areas.png]() In the figure, the arrow labelled F at the planet points back along the line toward the Sun S, while the arrow labelled v is along the orbit. What does the direction of F shown in the diagram tell you about the gravitational force?
   • A.It is a central force directed from the planet toward the Sun
   • B.It is directed along the velocity v, speeding the planet up
   • C.It is directed away from the Sun, pushing the planet outward
   • D.It is perpendicular to the line SP at every instant
5. 5.Assertion (A): A planet moves slower at aphelion than at perihelion. Reason (R): Conservation of angular momentum (m r v = constant) requires v to decrease as r increases.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
