There are four light weight rod samples A,B,C and D separately suspended by thread. A bar magnet is showly brought near each sample and the following observations are noted

A

C is a diamagnetic material

B

D is of a ferromagnetic material

C

A is of a non-magnetic meterial

D

B is of a paramagnetic material

Text Solution

Verified by Experts

The correct Answer is:
D
Paramagnetic materials will be feebly attract, diamgnetic material will be freely replied and ferromagnetic material will be strongly attracted.

Five Styrofoam balls are suspended from insulating threads. Several experiments are performed on the balls and the following observations are made: (i) Ball A repels C and attracts B. (ii) Ball D attracts B and has no effect on E. (iii) A negatively charged rod attracts both A and E. An electrically neutral Styrofoam ball gets attracted if placed nearby a charged body due to induced charge. What are the charges, if any, on each ball A,B,C,D, and E?

Figure shows an arrangement of four identical rectangular plates A,B,C, and D each of area S. Find the charges appearing on each face (from left to right) of the plates. Ignore the separation between the plates in comparison to the plate dimensions.

In the figure shown a uniform conducing rod of mass m and length l is suspended invertical plane by two conducing springs of spring constant k each. Upper end of springs are connected to each other by a capacitor of capacitance C. A uniform horizontal magnetic field (B_(0)) perpendicular to plane of springs in space initially rod is in equillibrium. If the rod is pulled down and released, it performs SHM. (Assume resistance of springs and rod are negligible) Find the period of oscillation of rod.

Read the following four statement A,B,C and D and select the right option having both correct statements. statements (A) Z scheme of light reaction takes place in presence of PS I only . (B) Only PS I is functional in cyclic photosporylation (C) Cyclic photophosphorylation results into synthesis of ATP and NADPH_(2) (D) Stroma lamellae lack PSII as well as NADP (a) A and B (b) B and C (c) C and D (d) B and D

The electron in a Li^(+ +) ion is the nth shell , n being very large. One of the K-electron in another matallic atom has been knocked out. The second matel has four orbits. Now, we take two sample one of Li^(+ +) ion and the other of the second mateillic ions. Suppose the probability of electronic transition from higher to lower energy level is directly proportional to the energy difference between the two shells. Take hc = 1224 eV nm , where h is Planck's constant and c the velocity of light in vacuum. It is found that major electromagnetic wavws emitted from the two sample are identical. Now , answer the following questions: What is the major X-ray emitted by the sample?

A sample of 2 kg of monatomic helium (assumed ideal) is taken through the process ABC another sample of 2 kg of the same gas is taken through the process ADC as shown in Fig. Given molecular mass of helium = 4. a. What is the temperature of helium in each of the states A, B, C and D ? b. Is there any way of telling afterwards which sample of helium went through the process ABC and which went through the process ADC ? Write yes or no. How much is the heat involved in each of the process ABC and ADC ?
