Answer 2

Explanation:

Given A force is expressed with respect to the basis and by equation 2(3+4) N. If the directions of makes an angle of 30 degree with, find the vector.

• So given force = 2 (3e1 + 4e2)
•                        = 6e1 + 8e2
• The direction e1 makes an angle equal to 30 degree
• So tan 30 = 8 e2 / 6 e1
•       1/√3 = 8e2 / 6e1
• Squaring both sides we get
•       1/3 = 64 e2 / 36 e1
•       36 e1 = 3 x 64 e2
•        Or e1 = 3 x 64 e2 / 36
•         Or e1 = 16 / 3 e2
