A verctor of magnitude ` 100 N` is inclined at an angle of ` 30^@` to another vector of magnitude ` 50 N`. Calculate the magnitude of dot rpdut and cross parodut fo two vectors.

Explanation

Here, ` A = 100 N, B= 50 N, theta= 30^@`
` vec A. vec b= AB cos theta = 100 xx 50 xx cos 30^@`
` |vec Axx vec B| = AB sin theta = 100 xx 50 cos 30^@`
`= 100 xx 50 xx 1//2 = 2500 N^2`.
