What is resultant magnetic force? can you please explain with an example. (Shreya) Answer: When a magnetic substance (or a magnet) is placed in a region where there are multiple magnetic fields, the net force due to all of them is called the resultant. In other words, it is that magnetic force which can effectively [...]
If maximum height attained by a body projected vertically upward is equal to two times magnitude of acceleration , then its time of flight is ………. ? (Divya posted) Answer: If you take g=10 m/s2 then H=20m At max height, v=0 H=vt- 0....

what’s effect of coulombic forces on conductor medium ? amk niazi Ans: In a conductor, the coulombian repulsive forces pushes the valence electrons and the electrons move away from the center to the surface ie from the region of stronger force to the region of lesser force, creating a Faraday cage Incoming search terms:what’s effect of coulombic forces on conductor [...]

“Can a body at rest make another body move,according to the laws of Newton this is impossible. The question is in magnetism, If it happens then why is it not predicted by classical mechanics?” (Priyoranajn asked) Answer: First of all I congratulate you for your genuine thought. It is the critical thinking which will lead [...]
