Contrast detected.

Haha
But I don't get this question. :$

Well, agreed.

sorry this is an AS level question
just misread site

Question number?

Dunno .. Sorry

I suck at Electronics now.. I use to just score in Electronics part but now its vice-verse :/

 

[Mayisha M]

OK, for b) part you need to know the concept of stationary waves. Do you have the physics coursebook?

Yes I do. Which page?

 

[lawman]

some waves notes for AS level hope they are useful to you as they are useful to me

But according to the b(ii) 1, center is the region showing constant field strength.
And when we are marking top or bottom, we show it towards the plane, right? So that covers both the lower and the decreasing part.

Not center of the plate. I mean between the sphere and the plate

I know right! Hate electricity as well!! BIG TIME!!

Y is B not like this ?

Because B is farther away from the nucleus. It's farthur away so the repulsion will be less with the nuclus. Hence less deflection. The deviation angle will be smaller.

Finally I got all of the answers of the paper Paper was easy, here you go, hope this is correct... resistance is zero so pwer is zero obvious and in infinite resistance no current passes so zero rsistance i guess...

It can't be like this the deviation is not the same as furthur away you get from the nucleus the less the nuclear repulsion

Thank you!!
But.. Why wouldn't Be B straight? :$ and explanation?

How sure are you that no force is acting on B
If you see from the fig you can see A has quite much deviation that means the nuclear charge is quite strong ans so B will still have deviation

Got it, ty :')

Got it, ty :')

can you help me with Q3 part c of the same paper

 

[Iridescent]

Not center of the plate. I mean between the sphere and the plate

I still think that showing it on top or bottom is better. It is obviously decreasing as the spacing of the lines is increasing.

can you help me with Q3 part c of the same paper

which paper was it ?
