Friction force acting on the block is?

A block of mass 1kg is pressed against a wall by applying a horizontal force of 10N on the block. If the coefficient of friction between the block and the wall is 0.5 ,magnitude of the frictional force acting on the block is

A block of mass 0.1 kg is held against a wall by applying a horizontal force of 5 N on the block. If the coefficient of friction between the block and the wall is 0.5, then the magnitude of the frictional force acting on the block is

A block of mass 10 kg is kept on a fixed rough (mu=0.8) inclined plane of angle of inclination 30^(@) . The frictional force acting on the block is

A block of mass 1 kg is placed on a truck which accelerates with acceleration 5ms^(-2) . The coefficient of static friction between the block and truck is 0.6. The frictional force acting on the block is

A force of 750 N is applied to a block of mass 102 kg to prevent it from sliding on a plane with an inclination angle 30^@ with the horizontal. If the coefficients of static friction and kinetic friction between the block and the plane are 0.4 and 0.3 respectively, then the frictional force acting on the block is
