Question

Given three vectors A = 24i + 33j, B = 55i - 12j and C = 2i + 43j (a) Find the magnitude of each vector. (b) Write an expression for the vector difference A - C. (c) Find the magnitude and direction of the vector difference A-B. (d) In a vector diagram show vector A + B, and A - B, and also show that your diagram agrees qualitatively with your answer.

Answer 1

Answer:

please ans its important

Explanation:

please ans its important

Answer 2

Answer:

a) magnitude of a vector xi^ + yj^ is

Explanation:

b) you can directly subtract vectors

c) LET |A-C|= X

squaring on both sides

mod A SQUARE PLUS MOD B SQUARE MINUS TWO TIMES THE SCALAR PRODUCT OF A AND B = X SQUARE

Calculate x

subtract vectors A AND B

let it be xi^+ yj^

tan theta = y/x

theta gives the Direction
