Find `vecA + vecB and vecA - vecB` in the diagram shown in figure. Given A = 4 units and B = 3 units.

If |vecA|= 4, |vecB|=3 and theta= 60^@ in the figure . Find vecA.vecB

If vecA = vecB + vecC and the magnitudes of vecA, vecB and vecC are 5,4 and 3 units respecetively, the angle between vecA and vecC is :

If veca , vecb are unit vectors such that the vector veca + 3vecb is peependicular to 7 veca - vecb and veca -4vecb is prependicular to 7 veca -2vecb then the angle between veca and vecb is

If veca , vecb are unit vectors such that the vector veca + 3vecb is peependicular to 7 veca - vecb and veca -4vecb is prependicular to 7 veca -2vecb then the angle between veca and vecb is

If veca and vecb are two unit vectors such that veca + 2 vecb and 5 veca - 4 vecb are perpendicular to each other, then the angle between veca and vecb is :

If veca and vecb are two unit vectors such that veca + 2vecb and 5 veca - 4vecb are perpendicualar to each other, then the angle between veca and vecb is

If veca and vecb are any two unit vectors, then find the greatest postive integer in the range of (3|veca + vecb|)/2+2|veca-vecb|

If veca and vecb are any two unit vectors, then find the greatest postive integer in the range of (3|veca + vecb|)/2+2|veca-vecb|

If veca and vecb are any two unit vectors, then find the greatest postive integer in the range of (3|veca + vecb|)/2+2|veca-vecb|

If veca and vecb are any two unit vectors, then find the greatest postive integer in the range of (3|veca + vecb|)/2+2|veca-vecb|
