Question

a body travelling eastward with 10m/s turns northwards nd travels with the same speed 10m/s. is there any accelaration

Answer 1

Change in velocity is 20
Yes there is acceleration..

Answer 2

The correct answer to the question is Yes i.e there exists an acceleration.

EXPLANATION:

Before coming into any conclusion, first we have to understand a vector quantity.

A vector quantity is  a physical quantity which requires both magnitude as well as direction for its complete specification, and is also in accordance with parallelogram law of vector addition.

Acceleration is defined as the rate  of change of velocity.  Hence, it is a vector quantity.

As per the question, the body moves 10 m/s east ward. After travelling east, it turns north ward and moves with the same velocity.

Here, the magnitude of velocity is same in both the cases, but, direction of motion is different . Hence, the change in direction will lead to an acceleration.
