Question

An ant travels a distance of 8cm from P to Q and then moves a distance of 6cm at right angles to PQ.Find it's resultant displacement

Answer 1

Answer:

please mark  me as brainliest

Explanation:

The ant travels a distance of 8 cm in a straight line from p to q and then moves 6 cm perpendicularly to the line pq.

Then the resultant displacement of the ant from p is the hypotenuse of the right angled triangle that is created by this movement.

Therefore, as per the mathematical formula, hypotenuse2 = 82 + 62 = 100.

Hence, the displacement of the ant = √100 = 10 cm, which is the longest side of a triangle.

Answer 2

Answer:

10 cm

Explanation:

Given :

• Distance of 8 cm is travelled from P to Q

• The ant then moves 6 cm in right angle to it

To find :

• Resultant displacement

Displacement is nothing but defined as the shortest distance covered by an object

So here Displacement will be equal to the Hypotenuse of the right triangle formed

So,

PQ²+QR²=PR²

8²+6²=PR²

64+36=PR²

100=PR²

PR = √ 100

PR = 10 cm

Hence the resultant Displacement will be equal to 10 cm
