MCQ
$A$ straight line joining the object point and image point is always perpendicular to the mirror
  • A
    if mirror is plane only
  • B
    if mirror is concave only
  • C
    if mirror is convex only
  • irrespective of the type of mirror.

Answer

Correct option: D.
irrespective of the type of mirror.
d
Any line joining the object point and the image point always passes through the centre of curvature of the mirror. This, is because of the law, that any ray passing through the centre of curvature of the mirror will retrace its path back.

Thus, any ray passing through the centre of curvature will be perpendicular to the mirror irrespective of the type of the mirror used.

Charges $-q$ and $+ q$ located at $A$ and $B$, respectively, constitute an electric dipole. Distance $AB = 2a$, $O$ is the mid point of the dipole and $OP$ is perpendicular to $AB$. A charge $Q$ is placed at $P$ where $OP = y$ and $y >> 2a$. The charge $Q$ experiences an electrostatic force $F$. If $Q$ is now moved along the equatorial line to $P'$ such that $OP' = \frac{y}{3}$, the force on $Q$ will be close to: $\left( {\frac{y}{3} >  > 2a} \right)$
