[" 20.If "a=hat i+hat j" and "b=2hat i-hat k" ,then the point of "],[" intersection of the lines "r times a=b times a" and "],[r times b=a times b" is "]

If bar = hat i + hat j and bar b = 2 hat i - hat k then the intersection piont of the lines bar r xx bar a = bar b xx bar a and bar r xx bar b = bar a xx bar b is .............

bar A = 2 hat i + 3 hat j and bar b = 3 hat i + 5 hat j Then bar a xx bar b is

If vec a = hat i - hat j and vec b = hat j + hat k then |vec a xx vec b|^(2) + |vec a. vecb|^(2) is equal to

If vec(a)= 3hat(i) + hat(j) + 2hat(k) and vec(b)= 2hat(i)-2hat(j) + 4hat(k) , then the magnitude of vec(b) xx vec(a) is

If vec a=hat i+2hat j-2hat k,vec b=2hat i-hat j+hat k and vec c=hat i+3hat j-hat k then find vec a xx(vec b xxvec c)

If vec (a) = 2 hat (i) - hat (j ) and vec (b) = 3 hat (i) - 2 hat (j) + 4 hat (k) , then the value of vec (a) xx vec (b) is -

If vec a=hat i-2hat j+hat k,vec b=2hat i+hat j-hat k and vec C=3hat i+5hat j+2hat k then find the value of vec a xx(vec b xxvec c)

If vec A = hat i + 3 hat j + 2 hat K and vec B = 3 hat i + hat j + 2 hat k , then find the vector product vec A xx vec B .
