QAIPMT-2010-Ph-2066: NEET 2010 Physics - Class 12 AIPMT-2010-Ph-2066 Solution: Which one of the following statement is false? Pure Si doped…
Which one of the following statement is false? Pure Si doped with trivalent impurities gives a p-type semiconductor. Majority carriers in a n-type semiconductor are holes. Minority carriers in a p-type semiconductor are electrons. The resistance of intrinsic semiconductor decreases with increase of temperature.
Multiple Choice Options
- A 1 s
- B 2 s
- C 3 s
- D 4 s
Step-by-Step Verified Solution
The time period T of oscillation of a magnet is given by
T = 2 � I M B
As I, B remains the same here
So T _ 1 B
or T 2 T 1 = B 1 B 2
_ T 2 = T 1 B 1 B 2
= 2 24 _ 10 _ 6 6 _ 10 _ 6 = 4 s
