Question

two vectors having magnitude of 6 Newton and 8 neuteon are inclined to each other at 90 degree than find R and angle made by R with 6N​

Answer 1

Solution is in the attachment

Answer 2

Answer:

Explanation:

a = 6; b = 8 ; R = ? ; Q = 90

=> R = √ ( a^2 + b^2 + 2 a . b . cos Q )

=> R = √ ( 6^2 + 8^2 + 2 . 12 . 13. cos 90 ° )

=> R = = √[36  + 64  + 312 (0)]

=> R = √100

=> R = 10
