Homework Statement
1. Two forces of equal magnitude are acting on a particle along two different directions. Let [tex]\theta[/tex]
be the angle between them. If direction of one vector is reversed , the magnitude of resultant is halved. Find tan[tex]\theta[/tex].
2.The resultant of the two vectors having magnitudes 5 and 4 is 1. what is the magnitude of their cross product?
Homework Equations
The Attempt at a Solution
for 1st one-
tan[tex]\theta[/tex] = Acos[tex]\theta[/tex][tex]\frac{}{}[/tex]A + Asin[tex]\theta[/tex]
and tan2[tex]\theta[/tex] = 2Acos[tex]\theta[/tex][tex]\frac{}{}[/tex]A + Asin[tex]\theta[/tex]
2nd one -
i get cos[tex]\theta[/tex] as -1.
