a.a = 4, b. b = 4 , a. b = 0
(a x b) c = 0
and (a x b). c = 8,

then
(a) a . c = 2
(c) c = 1
(b) b × c = 2a
(d) b. c = 2​

Answer 2

Answer:

Step-by-step explanation:

a, b, c are vectors such that

a.a = 4, b. b = 4 , a. b = 0

(a x b) c = 0

and (a x b). c = 8,

then

(a) a . c = 2

(c) c = 1

(b) b × c = 2a

(d) b. c = 2​
