A) \[\overrightarrow{v}\]remaining unchanged
B) less than \[\overrightarrow{v}\]
C) greater than \[\overrightarrow{v}\]
D) \[\left| \overrightarrow{v} \right|\] in the direction of the largest force BC
Correct Answer: A
Solution :
[a] From polygon law of vector addition we know if the vectors are arranged along the sides of a polygon the resultant of vector becomes zero. Here in this case the forces are represented by the sides of a triangle taken in same order, so their resultant is zero, it means the acceleration of the particle should be zero, hence velocity remains constant.You need to login to perform this action.
