हिन्दीA football player is moving southward and suddenly turns eastward with the same speed to avoid an opponent. The force that acts on the player while turning is :
Correct answer · Option D
along north-east
Explanation
Change in velocity \( \Delta \vec{v} = \vec{v}_f - \vec{v}_i = \vec{v}_{\text{east}} - \vec{v}_{\text{south}} = \vec{v}_{\text{east}} + \vec{v}_{\text{north}} \). Thus, the direction of acceleration and force is along north-east.
