A particle is moving in a circular path of radius R the displacement of the particleafter covering a1/4 of circle
Answers
Step-by-step explanation:
Given particle covers three quarters of a circle with radius R.
Distance travelled = 3/4(circumference of circle)
=3/4(2*pi* r)
= 3/2 ( pi* r).
DISPLACEMENT=SHORTEST PATH
= IF WE JOIN POINT A and B we get right angle triangle with
Hypotenuse(displacement) and other two sides of triangle with sides r.
Displacement =Sqr(r^2 +r^2)
=sqr(2r^2)
=r*sqr(2)
=1.41*r meters
Therefore Displacement covered by particle is 1.414*r m

Answer:
The displacement is the minimum distance between the initial position and final position.
Suppose a particle starts at a point A at the periphery of the circle and after covering half the circle, particle is at point B.
The minimum distance between points A and B is AB which is also the diameter of the circle.
Therefore, displacement after covering half the circle =Diameter=2r
