A block of weight `100N` is pushed by a force `F` on a horizantal rough plane moving with an acceleration `1m//s^(2)` when force is doubled its acceleration becomes `10m//s^(2)`. The coefficient of friction is `(10m//s^(-2))`

A block of weight 100N is pushed by a force F on a horizontal rough plane moves with an acceleration 1 m//s^(2) , when force is doubled its acceleration becomes, 10 m//s^(2) . The coefficient of friction is- ( g=10ms^(2) )

A block of mass 10kg pushed by a horizontal force F on a horizontal rough plane moves with an aceleration 5ms^(-2) . When force is doubled, its acceleration becomes 18ms^(-2) . The coefficient of friction is (g=10 ms^(-2) )

A block of mass 10kg is pushed by a force F on a horizontal rough plane is moving with acceleration 5ms^(-2) When force is doubled its acceleration becomes 18ms^(-2) Find the coefficient of friction between the block and rough horizontal plane (g =10ms^(-2)) .
