Question

Prove that a vector can be resolved along two directions in one and only one way. please do answer correct and fast guyz...

Answer 1

Answer:

A vector (A) in a 2-dimensional plane can have only two components one along the horizontal axis the other along the vertical axis as shown above and from the above figure it is clear that we can break it into components only by the help of trigonometry so, we can say that it could be done in only one way.

Answer 2

Answer:

       

Explanation: i only give hint to solve this q  of q

we have 2 component of 2 direction horizotal and veritical

so we take directional componential point which will be xcos theta

and y sinthea

so then put value for direction for horizontal

Fx=fcos

for vertical component

Fy=fsin

hope it will help you
