Question

find the distane and didplacement if particle starts from point a to point b from half circumference of the radius of 5 meter?​

Answer 1

Answer:

Distance = 15.7 meters             Displacement = 10 meters

Explanation:

                :Given Data:-

Circumference of Sphere = 2πr

Radius of Sphere = r = 5 meter

                  :To Find:-

Distance = d = ?

Displacement = d = ?

                   :Solution:-

• Distance = Total length covered

As, total length covered is the half of circumference. Therefore,

Distance = Half of Circumference.

   //         =  2πr / 2.

   //         =  2 x (3.14) x (5) / 2

Distance = 15.7 meters.

• Displacement = Shortest distance.

As, the shortest distance is the diameter of the sphere. Therefore,

Displacement = Diameter of Sphere.

      //                = 2r.

     //                 =  2 x 5.

Displacement = 10 meters.
