If `hat i` and `hat j` are unit vectors along mutually perpendicular directions then the magnitude of `hat i- hat j` is :

If hat(i), hat(j), hat(k) are unit vectors along three mutually perpendicular directions, then

If hat(i), hat(j), hat(k) are the unit vectors and mutually perpendicular, then [[hat(i), hat(j), hat(k)]] =

If hat i and hat j are unit vectors along X - and Y -axis respectively,then what is the magnitude and direction of hat i+hat j and hat i-hat j?

Assertion: If hat(i) and hat(j) are unit Vectors along x-axis and y-axis respectively, the magnitude of Vector hat(i)+hat(j) will be sqrt(2) Reason: Unit vectors are used to indicate a direction only.

Assertion: If hat(i) and hat(j) are unit Vectors along x-axis and y-axis respectively, the magnitude of Vector hat(i)+hat(j) will be sqrt(2) Reason: Unit vectors are used to indicate a direction only.

If (hat i, hat j, hat k) are the usual three perpendicular unit vectors, then the value of hat i*( hat j xx hat k)+ hat j*(hat i xx hat k)+ hat k*(hat i xx hat j) is

A unit vector along the direction hat(i) + hat(j) + hat(k) has a magnitude :

If hat(i) and hat(j) are unit vectors x and y axes repsectively , what is the magnitude and direction of hat(i) + hat(j) and hat(i) - hat(j) ?

If hat i , hat j and hat k are three mutually perpendicular vectors prove that hat i .(hat k xx hat j ) = hat j .(hat i xx hat k) = hatk ( hat j xx hat i ) = -1

For mutually perpendicular unit vectors hat(i), hat(j), hat(k) , we have :
