Newton's third law is not correct

AI Thread Summary
Newton's Third Law states that for every action, there is an equal and opposite reaction between two interacting bodies. The discussion identifies that statement D, claiming the forces are always equal in magnitude, is incorrect. It clarifies that the forces do not need to be of the same type (A) or act on different bodies (B) to satisfy the law. The focus is on the nature of the forces being equal and opposite, rather than their type or the bodies they act upon. Understanding this distinction is crucial for accurately interpreting Newton's Third Law.

Newton's Third Law concerns the forces of interaction between two bodies.
Which of the following statements relating to the third law is not correct ?

A. The two forces must be of same type
B. The two forces must act on different bodies.
C. The two forces are always opposite in direction
D. The two forces are at all times equal in magnitude.
E. The two forces are equal and opposite so the bodies are in equilibrium

Ans is D but why can't be A or B ?

MUST THE FORCES are of same type?

Who said that the proper response is D?

Can you explain to us the third law in your own words?

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...
