If `vec a=hati +hat j+hat k, vecb=hat i+hat j , vecc=hati and (bar a xx bar b)xx bar c=lambda bar a+mu bar b`, then `lambda+mu=`

If bar(a)=hati+hatj+hatk,bar(b)=hati+hatj,bar( c )=hati and (bar(a)xx bar(b))xx bar( c )=lambda bar(a)+mu bar(b) then lambda+mu = …………

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 bar a=hat i +hat j+ hat k, bar b=hat i-hat j +hat k, bar c=hat i +2hat j-hat k then the value of |[bar a.bar a, bar a.bar b, bar a.bar c],[bar b.bar a,bar b.bar b, bar b.bar c],[bar c.bar a,bar c.bar b,bar c.barc]|

If bar(P)=hat i+hat j+hat k,bar(Q)=2hat i-hat j-hat k , then bar(P)-bar(Q) 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 .............

If the vectors vec(a) = 2 hat (i) - lambda hat(j) + 3 hat (k), vec(b) = 3 hat (i) + 2 hat (k) - mu hat (k) and vec(c ) = hat (i) + hat (j) + hat (k) are coplanar , find mu in terms of lambda
