Question

ant makes five complete rounds around a bangle of diameter 7 c. m the final displacement of the ant is choose the correct answer. a) 35c. m b) 120 c. m c) 0c. m d)220c.m

Answer 1

as ant make five complete rounds. so ant will reach at same position where it starts. so displcement=0

Answer 2

Answer:

Final displacement of the ant is 0 cm .

Option (c) is correct .

Step-by-step explanation:

Definition of displacement

Displacement is the shortest distance travelled by an object .

Thus

Displacement = Final position - Initial position

As given

Ant makes five complete rounds around a bangle of diameter 7 cm .

As the after complete 5 rounds ant come to the same position from where ant starts thus the displacement in this case is 0 .

Therefore  final displacement of the ant is 0 cm .

Option (c) is correct .
