ps: if you are the one who left a comment at the blog on this qu, plz do not include links to the papers. Only refer to the year, variant, qu no.
thanks

for the 1st question.
the other one will be added soon
for q7, check solution 150 at

check again there for the others
But where is the pivot
Thank youYou just have to take moments about a point. You can take it from any point on the ladder. In this case to get the answer you take it from the highest point of the ladder and apply the formula
clockwise moments = anticlockwise moments
The upthrust will be the lowest because the force from the atmosphere pushing you upwards is the least as the atmosphere is very thin. The weight will be the greatest because it is the force that is making you fall down .Need help...
A ball is falling at terminal speed in still air. The forces acting on the ball are upthrust, viscous
drag and weight.
What is the order of increasing magnitude of these three forces?
A upthrust → viscous drag → weight
B viscous drag → upthrust → weight
C viscous drag → weight → upthrust
D weight → upthrust → viscous drag
Answer is A. But why?
Thank you !
Can someone explain Q 33 May June 2006 P1. I am not understanding how it will be a potential divider circuit and how to solve it.
ThanksThanks for the explanation.
As for your question,
Refer to solution 100 at
http://physics-ref.blogspot.com/2014/11/physics-9702-doubts-help-page-19.html
They are similar.
See if it helps.
