Question

If jhon is pulling a rope to the left with a force of 30 n,while tanu is pulling to the right with force of 45 n,the rope will move right with a force of l5n

Answer 1

Answer:Following Newton's third law (... equal and opposite forces...), the string stretches until it reaches its tightest point.You might imagine this to be like a tug-of-war game with both sides dead even.Since we are focusing on horizontal forces, and since exactly two horizontal forces are pulling in opposite vector directions to the same extent, these cancel each other out, as seen here:∑Fx=T−Fx=max=0 As stated in the question, it would mean that T=Fx (so T−Fx=0 ). Thus, if Fx=10 N , T=10 N .(Additionally, even if m is small, ax must therefore be 0 m/s2 .)Answer link
