Dynamics A Level Force Questions

AI Thread Summary
The discussion revolves around a physics problem involving two bodies, P and Q, that exert forces on each other with no other forces acting on them. According to Newton's third law, the force acting on Q is equal in magnitude to the force acting on P, which is F. The acceleration of Q can be determined using the equation F=ma, leading to the conclusion that the acceleration of Q is a function of its mass. The correct pair of answers is identified as the force on Q being F and the acceleration of Q being F/Mq. The conversation emphasizes the importance of understanding the underlying principles rather than merely guessing the answers.

Homework Statement


Two bodies P and Q having masses Mp and Mq respectively exert forces on each other and have no other forces acting on them. The force acting on P is F which gives P an acceleration a.Which of the following pairs is correct?

Magnitude of force on Q Magnitude of acceleration of Q

A. Mq/Mp*F a
B. Mp/Mq*F a
C. F a
D. F Mp/Mq*a
E. F Mq/Mp*a

Homework Equations


F=ma


The Attempt at a Solution



Magnitude of Force on Q: F because of Newton's third law
Magnitude of acceleration: a

Can you explain your reasoning for choosing that answer? Otherwise, for all we know, you just guessed, which doesn't exactly qualify for attempting to solve the problem yourself.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
