Find the scalr and vector products of two vectors vec a =(3 hat I - 4 hat j + 5 hat k) and vec b = (-2 hat I + hat j- 3 hat k).

The scalar product of the vector hat i+ hat j+ hat k with a unit vector along the sum of vector 2 hat i+4 hat j-5 hat k and lambda hat i+2 hat j+3 hat k is equal to one. Find the value of lambda .

Find lambda such that the scalar product of the vector vec i + vec j + vec k with the unit vector parallel to the sum of the vectors 2 vec i + 4 vec j - 5 vec k and lambda vec i + 2 vec j + 3 vec k is equal to 1.

The scalar product of the vector hat i+hat j+hat k with the unit vector along the sum of vectors 2hat i+4hat j-5hat k. and lambdahat i+2hat j+3hat k is equal to one.Find the value of lambda .

The scalar product of the vector i+j+k with a unit vector along the sum of vectors 2i+4j-5k and lambda i+2j+3k is equal to one.Find the value of lambda

The scalar product of the vector vec a=hat i+hat j+hat k with a unit vector along the sum of the vectors vec b=2hat i+4hat j-5hat k and vec c=lambdahat i+2hat j+3hat k is equal to 1. Find the value of lambda and hence find the unit vector along vec b+vec r

Assertion: The dot product of one vector with another vector may be scalar or a vector. Reason: If the product of two vectors is a vector quantity, then product is called a dot product.
