A particle is executing uniform circular motion with velocity v and acceleration a . Which of the following is true?

Options

  1. Av is a constant; a is a constant
  2. Bv is not a constant; a is a constant
  3. Cv is a constant; a is not a constant
  4. Dv is not a constant; a is not a constant

Correct answer

D. v is not a constant; a is not a constant

Step-by-step solution

v is not a constant; a is not a constant In uniform circular motion v keeps changing at every instant while magnitude of a remains same but its direction keeps changing. Thus a is also not constant.
