Answer:
displacement is distance between final position to initial in straight line so after half circle displacement is 2R so 2×7= 14 cm ans after two rounds of circle particle again at same position means intial position then no displacement
Answer:
Explanation:
FIRST CALCULATE THE CIRCUMFERENCE OF CIRCLE,
2πR,
2×7×22/7,
2×22,
44 CM,
S0,DISPLACEMENT OF HALF CIRCLE IS 44/2 CM,
22 CM,
AND,DISPLACEMENT IN TWO ROUNDS IS 44×2,
88 CM.
