We subtract the two to get the resultant force. Frictional force opposes the driving force and so the total force becomes 2N.
please help

as far as i know it's significant figures.
u need to MULTIPLY THE PERCENTAGE UNCERTINITY OF L BY 2
Let's assume l is 10.2 (+- 0.4). When l is squared, we square the two extreme points and subtract them to get uncertainty in the l squared value.
10.2^2 = 104.04 and uncertainty = (10.2+0.4)^2 - (10.2-0.4)^2
= 10.6^2 - 9.8^2
= 112.36 - 96.04 = 16.32
So, we have 104.04 (+- 16.32).
Hope you get it.

Thank you so much!
owwhokk.
my sir told me its decimal place, whereas mark scheme also show that sig fig shud remain same thru out the column.. :/
Thanks btw.JazakAllah khair!
