A particle moves in a circle of radius 4 cm clockwise at constant speed of 2 cm s -1 . If 
and 
are unit acceleration vectors along x and y axes, respectively, the acceleration of the particle at the instant half way between PQ is given by
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Midpoint acceleration,
a = 
at 45 0 with x axis
∴ ∴ 
= -1 × 
Thus
