A point P consider at the contact point of a wheel on the ground which roll on the ground without slipping, then the value of the displacement of point P\mathrm{P} when wheel completes half of the rotation (if radius of wheel is 1 m1 \mathrm{~m} )is:A point P consider at the contact point of a wheel on the ground which roll on the ground without slipping, then the

Options

  1. A2 m2 \mathrm{~m}
  2. Bπ2+4 m\sqrt{\pi^2+4} \mathrm{~m}
  3. Cπm\pi \mathrm{m}
  4. Dπ2+2 m\sqrt{\pi^2+2} \mathrm{~m}

Correct answer

B. π2+4 m\sqrt{\pi^2+4} \mathrm{~m}

Step-by-step solution

A point P consider at the contact point of a wheel on the ground which roll on the ground without slipping, then the Displacement PQP Q=(PM)2+(QM)2=(πR)2+(2R)2=π2+4{∵R=1 m}\begin{aligned} & =\sqrt{(P M)^2+(Q M)^2} \\ & =\sqrt{(\pi R)^2+(2 R)^2} \\ & =\sqrt{\pi^2+4}\{\because R=1 \mathrm{~m}\} \end{aligned}$$
