Three forces F 1 = 10 N , F 2 = 8 N , F 3 = 6 N are acting on a particle of mass 5 kg . The forces F 2 and F 3 are applied perpendicularly so that particle remains at rest. If the force F 1 is removed, then the acceleration of the particle is

Step-by-step solution

When the force F 1 is removed, the particle starts accelerating because of the resultant force between F 2 and F 3 . The resultant force can be calculated as follows: F = F 2 2 + F 3 2 = 10   N Hence, the acceleration of the particle is given by a = 10   N 5   kg = 2   m   s – 2
