Meena applies the front brakes while riding on her bicycle along a flat road. The force that slows her bicycle is provided by the

Options

  1. Afront tyre
  2. Broad
  3. Crear tyre
  4. Dbrakes

Correct answer

B. road

Step-by-step solution

The frictional force on the tyres is an external force and is being provided by the road. Other options i.e. front tyre, rear tyre and brakes comprise the internal parts of bicycle thus forces applied by them will be internal only.
