MCQ
Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then,
  • A
    negative and distributed uniformly over the surface of the sphere
  • B
    negative and appears only at the point on the sphere closest to the point charge
  • C
    negative and distributed non-uniformly over the entire surface of the sphere
  • zero

Answer

Correct option: D.
zero
d

A small block of mass $m$, having charge $q$ is placed on frictionless inclined plane making an angle  $\theta$ with the horizontal. There exists a uniform magnetic field $B$ parallel to the inclined plane but  perpendicular to the length of spring. If $m$ is slightly pulled on the inclined in downward direction and released, the time period of oscillation will be (assume that the block does not leave contact with the plane)
