Question

In Figure CQ4.16, the light, taut, unstretchable cord B joins block 1 and the larger-mass block 2. Cord A exerts a force on block 1 to make it accelerate forward. (a) how does the magnitude of the force exerted by cord A on Block 1 compare with the magnitude of the force exerted by cord B on block 2? Is it larger, smaller, or equal? (b) How does the acceleration of block 1 compare with the acceleration (if any) of block 2? (c) Does cord B exert a force on block 1? If so, is it forward or backward? Is it larger, smaller, or equal in magnitude to the force exerted by cord B on block 2?

Explanation / Answer

Fa=(m1+m2)a Fb=m2a a)so Fa/Fb=(m1+m2)/m2 ,,, so fa>fb b)acc of both are same c)yes. backward . mag=-m2a,,, it is equal to Fb but opposite in dir d)
