Question

A body is moving a circular path of radius 63m .what will be the distance covered and the displacement of the body after half a revolution

Answer 1

Answer

• Distance = 198 m
• Displacement = 134 m

Exolanation

Given

• A body is moving on a circular track
• Radius = 63 m
• It covers half of the path

To Find

• Distance and displacement of the body

Solution

• Distance will be half the circumference and displacement will be equal to the diameter of the circular path

✭ Ditance Covered

• So here we shall find the circumference and then Divide it by 2 and find the distance travelled!!

→ Circumference = 2πr

→ Circumference = 2 × 22/7 × 63

→ Circumference = 2 × 22 × 9

→ Circumference = 396 m

Then the distance covered will be,

→ Distance travelled = Circumference/2

→ Distance = 396/2

→ Distance = 198 m

✭ Displacement

• Displacement will be equal to the diameter as it is the shortest path

→ Displacement = Diameter

→ Diameter = 2×Radius

→ Displacement = 2×Radius

→ Displacement = 2×67

→ Displacement = 134 m
