If `bar A= 2hati+8hatj+7hatk` and `bar B=3hati+2hatj` then the component of `(barA+barB)` along x-axis is

If vec A=hati +7hatj +hatk and vec B =2 hati+3hatj +4hatk then the component of vec A along vec B is

If the position vectors of A and B are hati+3hatj-7hatk and 5hati-2hatj+4hatk , then the direction cosine of AB along Y-axis is

The position vectors of points A and B are hati+3hatj-7 hatk and 5hati-2hatj+4hatk respectively, then the direction cosine of bar(AB) along Y-axis is

If a=2hati+2hatj-8hatk and b=hati+3hatj-4hatk , then the magnitude of a+b is equal to

If vecA=5hati-2hatj+3hatk and vecB=2hati+hatj+2hatk , component of vecB along vecA is

Let barA= hati + 2hatj + 3hatk and vec B = 3hati + 4hatj + 5hatk The value of the scalar sqrt(|bar A times barB|^2+(barA.barB)^2) is equal to

IF bar a = hati + hatj + hatk , bar b = 2 hati + lamda hatj +hatk , bar c = hati - hatj +4hatk and bar a .(barb xxbarc)=10 then lamda is equal to

If bara =3 hati - 2hatj +7 hatk, barb = 5hati + hat j -2 hatk and barc = hati + hatj - hat k, " then find "bara * (barb xx barc) .

The two vectors A=2hati+hatj+3hatk and B=7hati-5hatj-3hatk are -
