Blocks of $2 kg$ and $3 kg$ on a frictionless surface are joined by a wire of area $0.04 m m^{2}$ and breaking stress $2.5 GPa$ . Maximum force applied to the $3 kg$ block is:

Options:

Answer:

Solution:

$T_{m a x} = 2.5 \times 1 0^{9} (0.04 \times 1 0^{- 6}) = 100 N$ .

$a = \frac{T}{2} = 50 m/ s^{2}$ .

$F = (2 + 3) a = 250 N$ .
