Concept:

  • Force exerted on an object is directly proportional to the mass of the object and the rate at which it is accelerated
  • F = m × a
  • And for converting vector quantity to its scalar quantity, it can be given as

 

Here x, y, and z are a magnitude of vector r along X, Y, and Z-axis respectively.

Calculation:

Given that,

Accelerated (a) = 5 m/s2

Thus, the magnitude of force will be

Now the force is expressed as mass times acceleration,

i.e., F = m × a ⇒ m = F / a
