Type: MCQ-numerical-Hard-Class 11
A particle moves from position r(t1) to r(t2) in a plane. If the displacement is given by [r(t2) - r(t1)] and the time interval by (t2 - t1), which of the following expressions correctly represents the average velocity of the particle?
A
v_average = [r(t2) - r(t1)] / (t2 - t1)
B
v_average = (1/2) (v(t1) + v(t2))
C
v_average = [v(t2) - v(t1)] / (t2 - t1)
D
v_average = r(t1) + v(t2) / t1
Correct Answer
Option A
Detailed Explanation
Option A correctly uses the formula v_average = [r(t2) - r(t1)] / (t2 - t1) given in the NCERT context for average velocity over a time interval.
