QNEET-2023-Ph-354: NEET 2023 Physics - Class 11 NEET-2023-Ph-354 Solution: A particle is executing uniform circular motion with velocity…

A particle is executing uniform circular motion with velocity v⃗\vec{v} and acceleration a⃗\vec{a}. Which of the following is true? v⃗\vec{v} is a constant; a⃗\vec{a} is not a constant v⃗\vec{v} is not a constant; a⃗\vec{a} is not a constant v⃗\vec{v} is a constant; a⃗\vec{a} is a constant v⃗\vec{v} is not a constant; a⃗\vec{a} is a constant

Multiple Choice Options

  • A v⃗\vec{v} v is a constant; a⃗\vec{a} a is not a constant
  • B v⃗\vec{v} v is not a constant; a⃗\vec{a} a is not a constant
  • C v⃗\vec{v} v is a constant; a⃗\vec{a} a is a constant
  • D v⃗\vec{v} v is not a constant; a⃗\vec{a} a is a constant

Step-by-Step Verified Solution

Direction of velocity and centripetal acceleration changes continuously so v _ is not constant and a _ is not a constant.
