In the figure shown, the coefficient of static frictionbetween the block A of mass 20 kg and horizontaltable is 0.2. What should be the minimum mass ofhanging block just beyond which blocks start moving?20 kgAp = 0.2B0(1) 3 kg(2) 2 kg(3) 4 kg(4) 5 kgneed ans with solution !​

Answered by admin @


Answer:

4kg

Explanation:

n=200

frictional force =0.2*200=40n

so 4kg block will provide 40n tesion on string
