Resultant magnetic force

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.

Is the equation for displacement in the n th second dimensionally correct?

Is the equation for displacement in the n th second dimensionally correct? S = u + a (n- 1/2) Answer: Yes See the explanation given by Vimal Raj If we notice the derivation of this formula let t1=x and t2=y (for my easiness) S(y)=uy + 1/2 ay^2———-(1) S(x)=ux + 1/2 ax^2———–(2) sub (2) from (1) S(y)-S(x)=uy…… Continue reading Is the equation for displacement in the n th second dimensionally correct?
