Mechanics M1: Post your doubt here

What does it mean by magnitude of the resultant force there ? oO'

It means the modulus of the resultant force. for e.g the resultant force is -4i+3j
its magnitude becomes (squareroot)[ (-4^2) + (3^2) ] which is 5

Thank you mates . TeKnOzOr timing is usually a problem for everyone. Try to be fast during your calculations but at the same time accurate too, otherwise its useless. Try to complete all the workings on time and make sure to maintain them neat and clean but if you just have few minutes left and a lot of questions to workout with then forget the above tips and just try to complete the works within time limit but make your that the one who is going to check your papers is at-least going to understand it. Something is better than nothing, isn't it ?

Work out the paper ... take your time. but one advice would be not to stress yourself ... even tomorrow before the exams just keep cool and of course keep a check on the time. Do not discuss anything before the exam ... you'll be confused and you'll panick. So simply keep cool and all the best.

question 5 part 2 why in equation are we not subtracting the tension from the weight???? according to my prespective my equation shuld be 2g -(T+4) = 2a bt it is 2g + T -4 = 2a can anyone help me

you have two boxes A and B. lets see what are the forces acting on A and B

forces acting on box A,

the Ts1 upwards and the air resistance 1.6N upwards and its weight acting downwards

forces acting on box B,

the Ts2 downwards and with the weight acting downwards and the air resistance acting upwards.


i guess now its easy to do the calculations. anyway i have 2 ways of answering this question one is applyin newton second law to each of the boxes or u can do it in a faster way to the combined boxes.

if u need further help to this question pls do ask me!

so guys are you ready for tomorrow ? inshallah you all get the grade you want

this is what i want to ask that why is tension in B acting downwards???? as they bth are attached to a single rod and the tension is a cting upwards in A so will in B ?????
