Question

Two particles start moving from same position on a circle of radius 20 cm with speed
401 m/s and 3611 m/s respectively in the same direction. Find the time after which the
particles will meet again.

Answer 1

Answer:

Two particle start from the same position on a circle of radius=20cm

The speed =40πm/s

and 36πm/s

Relative velocity of the first particle with respect to the slow one

(40π−36π)m/s

=4πm/s

The circumference distance covered with this relative yer,

4π=

T

2πR

(where R= radius T= time period)

T=

4π

2πR

The Constitution established a Federal democratic republic. It is the system of the Federal Government; it is democratic because the people govern themselves; and it is a republic because the Government's power is derived from its people.
