Question

In the figure below, the objects are attached to spring balances calibrated in newtons. Give the readings of the balances in each case, assuming that the strings are massless and the incline is frictionless.

I do not know how to solve for (b) or (d).

Explanation / Answer

b)T=10g since both the blocks should be in equilibrium.

T=98N

d)T=10gSin30 (for equilibrium)

T=5g=49N
