N-type crystals have:
Correct answer: B. Negative
- A. Positive
- B. Negative
- C. Neutral
- D. None of these
Explanation
N-type crystals are doped semiconductors where the majority charge carriers are electrons. These electrons contribute to a negative charge, hence N-type crystals have a negative charge.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.

wire, suspended vertically from one end, is stretched by attaching a weight of 20 N to the lower end. The weight stretches the wire by 1 mm. How much energy is gained by the wire
When a force is applied at one end of an elastic wire, it produces a strain e in the wire. If Y is the Young's modulus of the material of the wire, the amount of energy stored per unit volume of the wire is given by:
