A force of 200N is applied as shown in the figure on block of 3 kg. The coefficient of friction between the block and the wall is 0.3. Find the friction acting on the block. (in N) {Take g = 10 `m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
30
`F_(max)=mu mg`
`=3xx200=60N`
but friction would be equal to mg =30 N
