Two blocks are tied with a wire and are hanged over a pulley as shown. Masses of blocks are \( 1 \mathrm{~kg} \) and \( 4 \mathrm{~kg} \) and pulley is frictionless.

With reference to the above situation, which of the following is an incorrect statement?
(a) Tension in wire is \( 10 \mathrm{~N} \).
(b) Tension in wire is \( 16 \mathrm{~N} \).
(c) If breaking stress is \( 3.18 \times 10^{9} \mathrm{Nm}^{-2} \), then wire must be of \( 4 \times 10^{-5} \mathrm{~m} \) radius so that wire does not break.
(d) None of the above
\( \mathrm{P} \)
