NEETPhysicsMotion in A Straight LineMCQ+4 / −1

In some appropriate units, time (t)(t)(t) and position (x)(x)(x) relation of a moving particle is given by t=x2+xt=x^2+xt=x2+x. The acceleration of the particle is

  1. A
    +2(x+1)3+\frac{2}{(x+1)^3}+(x+1)32​
  2. B
    +22x+1+\frac{2}{2 x+1}+2x+12​
  3. C
    −2(x+2)3-\frac{2}{(x+2)^3}−(x+2)32​
  4. D
    −2(2x+1)3-\frac{2}{(2 x+1)^3}−(2x+1)32​
