Question

A car initially traveling eastwards turns north by traveling in a quarter circular path of radius $R$ metres at uniform speed as shown in figure. The car completes the turn in $T$ second
Which of the following is correct.

• A. average velocity of car during $T$ second period is $\frac{\sqrt{2}R}{T}m/s$ towards E-N
• B. average velocity of car during $T$ second period is $\frac{\sqrt{2}R}{T}m/s$ towards N-W
• C. Friction force on car acting during motion is always towards O and has constant magnitude
• D. Friction force on car acting during motion is always towards O and is constant

Answer 1

Answer: (A), (C)

The correct options are
A average velocity of car during $T$ second period is $\frac{\sqrt{2}R}{T}m/s$ towards E-N
C Friction force on car acting during motion is always towards O and has constant magnitude
