QAIPMT-2011-Ph-1905: NEET 2011 Physics - Class 12 AIPMT-2011-Ph-1905 Solution: There are four light-weight-rod samples A B C D separately…
There are four light-weight-rod samples A B C D separately suspended by threads. A bar magnet is slowly brought near each sample and the following observations are noted (i) A is feebly repelled (ii) B is feebly attracted (iii) C is strongly attracted (iv) D remains unaffected Which one of the following is true? B is of a paramagnetic material C is of a diamagnetic material D is of a ferromagnetic material A is of a non-magnetic material
Multiple Choice Options
- A 10 mA
- B 100 mA
- C 200 mA
- D 20 mA
Step-by-Step Verified Solution
e 0 = 200 2 V, _ = 100 rad s -1
The capacitive reactance is
X C = 1 _ C = 1 100 _ 1 _ 10 _ 6
The r.m.s. value of the current in the circuit is
i r.m.s = V r m s X C = e 0 2 1 _ C
= 200 2 2 1 100 _ 10 _ 6
= 200 _ 100 _ 10 �6 A = 2 _ 10 �2 A = 20 mA
