ASSERTION - REASON TYPE
Read the assertion and reason carefully to mark the correct option out of the options given below.
(A) If both assertion and reason are true and the reason is the correct explanation of the asseration.
(B) If both assertion and reason are true but reason is not the correct explaination of the asseration,
(C) If assertion is true but reason is false.
(D) If the assertion and reason both the false.
(E) If assertion is false but reason is true.
131. Assertion : We cannot think of magnetic field configuration with three poles.
Reason : A bar magnet does exert a torque on itself due to its own field.
132. Assertion : If a compass needle be kept at magnetic north pole of the earth, the compass needle may stay in any direction.
Reason : Dip needle will stay vertical at the north pole.
133. Assertion : Dia-magnetic materials can exhibit magnetism.
Reason : Dia-magnetic materials have permanent magnetic dipole moment.
134. Assertion : A paramagnetic sample displays greater magnetisation when it is cooled.
Reason : The magnetisaution does not depend on temperature.
135. Assertion : Two short magnets are placed on a cork which floats on water. The magnets are placed such that the axis of one produced bisects the axis of other at right angles. Then the cork has neither translational nor rotational motion.
Reason : Not force on the cork is zero.
136. Assertion : Cyclotorn does not accelerate electron.
Reason : Mass of the electron is very small.
137. Assertion : Cyclotron is a device which is used to accelerate the positive ion.
Reason : Cyclotron frequency depends upon the veolocity.
138. Assertion : The magnetic field produced by a current carrying solenoid is independent of its length and cross-sectional area
Reason : The magnetic field inside the solenoid is uniform.
139. Asseration : Torque on the coil is the maximum, when coil is suspended in a radial magnetic field.
Reason : The torque tends to rotate the coil on its own axis.
