A vector has component along the X-axis ...

A vector has component along the X-axis equal to 25 unit and along the Y-axis equl to 60 unit. Find the magnitude and direction of the vector.

Text Solution

Verified by Experts

The given vector is the resultant of two perpendicular vectors, one along the X-axis of magnitude 25 unit nd the other long the Y-axis of magnitude 60 units. The resultant has a magnitude A given by `A=(sqrt(25)^2+ (60)^2+2xx25xx60 cos 90^0)`
` = (25)^2+(60^2))=65` ltbr. The angle alpha between this vector and the X-axis is given by `tan alpha = 60/25`
