hi anyone can plz help me out urgently solving question 4 paert (b)

She then repeats the procedure with the lens at a distance x=30 cm from the illuminated object

(i) On Fig 4.1 measure the distance Xs between the lens and the illuminated object. Also on Fig 4.1, measure the distance Ys between the lens and the screen

anyone plz help me out....some hours are only left for my physics exam
thx a lot

thx a lot




xs = 5.0(cm) and ys = 5.2(cm)


i hope this ans ur ques

The connection  is halfway along the resistor AB. The resistor CD is commected to A bu t has no other connecting wire.

If you want to know why the websites are so slow, xtremepapers.com has been disabled so students are going to freeexampapers for past igcse papers.

You have to find the scale factor SF= x/xs=30/xs where xs  is found by measuring x on the paper.Then y=SF*ys

No the voltmeter should be connected to the midpoint of the resistor with an arrow to show that you can move the contact point.

Im also confused on the same question.  I also dont get B (II-IV)
Could someone plx explain if any formulas are used ? because it says only 2/3 sf in the mark scheme.

What distance do you measure on the paper for x? Say and I will do the calculations
