Sample questions

1. 1.An electric dipole of moment 4 x 10^-9 C m is aligned at 30 degrees to a uniform field of 5 x 10^4 N/C. The magnitude of the torque on the dipole is:
   • A.1 x 10^-4 N m
   • B.2 x 10^-4 N m
   • C.1.73 x 10^-4 N m
   • D.0.5 x 10^-4 N m
2. 2.Assertion (A): The flux through a closed surface depends only on the charge enclosed, not on charges outside. Reason (R): The electric field on the surface, whose flux is computed, is produced only by the enclosed charges.
   • 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
3. 3.For a uniformly charged thin spherical shell of total charge q and radius R, the electric field at a point inside the shell (r < R) is:
   • A.Zero
   • B.q/(4*pi*epsilon0*r^2)
   • C.q/(4*pi*epsilon0*R^2)
   • D.sigma/(2*epsilon0)
4. 4.A system contains five charges in arbitrary units: +1, +2, -3, +4 and -5. The total charge of the system is:
   • A.-1
   • B.+15
   • C.+1
   • D.-15
5. 5.The electric field due to a point charge Q is defined operationally using a test charge q, yet E is independent of q because:
   • A.The force F is proportional to q, so the ratio F/q does not depend on q
   • B.The test charge is always taken as 1 C
   • C.The field is created by the test charge
   • D.F is independent of q
