Question

if |a|=3|b|=4 and the angle between a and b is 120 then | 4a+3b | is equal to​

Answer 1

Answer:

12

step by step explanation :

Magnitude of vector a = 3

Magnitude of vector a = 3Magnitude of vector b = 4

Magnitude of vector a = 3Magnitude of vector b = 4

Magnitude of vector a = 3Magnitude of vector b = 4 magnitude of vector 4a = 12

Magnitude of vector a = 3Magnitude of vector b = 4 magnitude of vector 4a = 12magnitude of vector 3b = 12

Magnitude of vector a = 3Magnitude of vector b = 4 magnitude of vector 4a = 12magnitude of vector 3b = 12

Magnitude of vector a = 3Magnitude of vector b = 4 magnitude of vector 4a = 12magnitude of vector 3b = 12 angle between vector a & vector b = 120

Magnitude of vector a = 3Magnitude of vector b = 4 magnitude of vector 4a = 12magnitude of vector 3b = 12 angle between vector a & vector b = 120angle between vector 4a & vector 3b = 12
