Question

A block of mass 4 kg is resting on a vertical wall having coefficient of friction. 4 find the minimum force required to hold the block in position​

Answer 1

Answer:

Solution is in the attachment

Answer 2

The vertical component of force should be equal to wieght of the object

F/sin45=mg

$f \div \sqrt{2} = 4 \times 10 \\ f = 40 \times \sqrt{2} \\ f = 56.56 \\ force \: required \: = 56.56n$
