A particle initially at rest is subjected to two forces . One is constant, the other is a retarding force proportional to the particle velocity . In the subsequent motion of the particle :

  • (A):the acceleration will increase from zero to a constant value
  • (B):the acceleration will decrease from its initial value to zero
  • (C):the velocity will increase from zero to maximum & then decrease
  • (D):the velocity will increase from zero to a constant value.
