Load Q is a metal cylinder with diameter a little larger than the width of the metre rule, so
that it covers the markings on the rule. Load Q is placed carefully on the balanced metre rule
with its centre at the 84.2 cm mark. The rule does not slip on the pivot.

YOU read the question properly .. dude jus kiddin' it happens

Why is the image upside down?

It's a convex lens.
When the object is NOT within the focal length of the lens, it is inverted, ALWAYS.

Also, is the image we draw supposed to be 5 times magnified too?

Good Luck for tomorrow, everyone!
InshAllah, it'll be easy, and will go awesome for everyone. InshAllah!
Best of luck!

"An electron beam is equivilent to an electric current, but without the wire. It can bla bla bla.... In this diagram, the magnetic field is at right angles to the electron beam, so the beam is deflected."
This is what my book says... but how come the electrons go down (srry for bad quality). If u use Flemingooo's left hand rule, the current is ur middle finger(so points to the left [direction of electrons]), the field is ur second finger (pointing into the paper[direction of magnetic field]) and so ur thumb will be pointing up, which shows how the electrons will be deflected...How come they show it going down?

So how do we know where's the focal length in the diagram?
Yeah the ms says it'll be upside down, and i think it'll also be magnified since the magnification is 5.2

for those of u who asked abt the electrodeswho r immersed in water and how to measure them while they're immersed.....my tutor said that u use a divider ..........u open it where one end in at one of the electrodes and the other end is at the other electrode .. u get it out and then measure the distance between the two ends of the divider  .. " if u r wonderin what's a divider .. u kno when u buy a geometric box thingy ..well it's the thing that has long two legs which is right next to the compass "

hope i helped

gd luck people of da universe ..allah yiwafi8na jamee3an , AMEEN!!

I dnt think so we hav to draw it as magnified...If that would be the case they would mention it...Atleast in MS

Well, they say the image forms on the screen.
If it were within the focal length,  the upright image would be virtual thus impossible to project.
So, the only image projectable, is an upside down one.
