MCQ
The speed of light depends:
- AOn elasticity of the medium only.
- BOn inertia of the medium only.
- COn elasticity as well as inertia.
- ✓Neither on elasticity nor on inertia.
✓
Answer
Correct option: D.
Neither on elasticity nor on inertia.
The speed of light in any medium depends on the refractive index of that medium, which is an intensive property. Hence, speed of light is not affected by the elasticity and inertia of the medium.

In an ink-jet printer, an ink droplet of mass $m$ is given a negative charge $q$ by a computer-controlled charging unit, and then enters at speed $v$ in the region between two deflecting parallel plates of length $L$ separated by distance $d$ (see figure below). All over this region exists a downward electric field which you can assume to be uniform. Neglecting the gravitational force on the droplet, the maximum charge that can be given so that it will not hit a plate is close to :
