Question

R1, and R2 are two position vectors making angles theta 1 theta 2 and with positive x-axis respectively. Their vectorproduct is:[R1 = 4cm, R2 = 3cm, 01, = 30°, 02 = 90°)​

Answer 1

Answer:

|R3|= 6√3 along Z-axis

Explanation:

|R1| = 4 ; |R2| = 3 @1 = 30° ; @ = 90°

now vector product,...

|R1 × R2 |= |R1| |R2| (sin @2 - @1)

= 4 × 3 × sin (90° - 30°) = 4 × 3 × √3/2

|R1 × R2 | = 6√3 cm

this vector is along Z-axis
