(1) Directive properties: When a magnet suspended freely it remains in the earth's N-S direction (in magnetic meridian).
(2) Monopole concept: If a magnet is broken into number of pieces, every piece changes into a magnet. This in turn implies that monopoles do not stable.
(3) For two rods as shown, if both the rods attract in case (i) and doesn't attract in case (ii) then, B is a magnetic and A is linear iron shield. Repulsion is sure test of magnetism.
Displacement: - The modification in position of a body in a certain direction is known as displacement. It is a vector function and its unit in SI system is meter.
working model needed.........please help!!!!!!!!!!!!
Historical development of atomic models In olden days there was an idea that all matter is made of tiny indivisible particles. When Thomson discovered electron, this idea
Two stable isotopes of lithium and have respective abundances of 7.5% and 92.5%. These isotopes have masses 6.01512 u and 7.01600 u, respectively. Find the atomic mass of lithium.
a) A positive point test charge q 0 is placed at the midpoint p among the two equal positive charges q. What forces acts on it at or near this point p? b) Two charges 1X10 -
electric field
just after cutting of spring will extension becomes zero or not
What is quantisation of electric charge?
If two forces P & Q act at such an angle that the resultant force r=p. Then show that if P is doubled the new resultant is at right angle Q and it's value is ( 4P 2 -Q 2 ) 1/2
Radio active series There are three radio active series depending on their progenitor. They are i) Uranium series called (2n+2) series, ii) Actino-Uranium series, call
