(a) and (b) + (c) - - 2

Answer 1

typos?

Answer 2

Let = 2 î + 3 ĵ and = 2 î - 2 ĵ. Find the magnitude of the following.
(a) Eand F (b) E+F (c) -E – 2F

Answer 3

Do you read what you type? Do you perhaps mean
Let E = 2 î + 3 ĵ and F = 2 î - 2 ĵ. Find the magnitude of the following.
(a) E and F (b) E+F (c) -E – 2F

I will do two of them
magnitude of E = sqrt (4+9) = sqrt(13)

magnitude of E+F
= magnitude of 4 i + 1 j
= sqrt (16 + 1) = sqrt(17)
