Question

Q.
Q Two Vector P and a have maenitucles three
units and four units respecte bali R is the
I resaltant of P and o. find the magnitude
Land directices of Ŕ when the angle ou
between B and 2 is 30. 0
​

Answer 1

⭐《ANSWER》

VECToR RESULTANT

P = 4 AND Q = 3

and ⊙ = 30°

Resultant R" =

Underoot P^2 + Q^2 + 2PQ COS⊙

R^2 = 16 + 9 + 2 (4)(3) Cos 30°

R^2 = 25 + 12 root 3

thus , R = underoot 25 + 12root3
