Answer:

Magnitude force of friction is 235.2 N

Explanation:

The force of friction is the product of weight and the coefficient of static friction

The force have to be bigger than 200N because it don't move

∑F= $F_{n} - F_{fr}$

$F_{fr} = u*m*g\\F_{fr} = 0.80*30kg*9.8 \frac{m}{s^{2} } \\F_{fr} = 235.2 \frac{kg*m}{s^{2} } \\F_{fr} = 235.2 }$ N
