The coefficient of static friction between two blocks is $0.5$ and the table is smooth. The maximum horizontal force that can be applied to move the blocks together is _______ $N$ (take $g = 10 {m s}^{- 2})$

Answer:

15.00

Solution:

For $F_{\max}$ with relative rest, $f_{s}$ between

$2 kg & 1 kg$ must be maximum.

$A_{comm o n} \leq a_{\max}$

$\frac{F}{3} \leq \frac{10}{2}$

$F \leq 15$
