as j dot j = 1 , so the product of j and j is only the scalar magnitude, with no unit ?QuantumQuest said:What is the dot product of j.j ? You have to understand why, for each such unit vector, this dot product is 1. As a hint, take the definition of dot product.

The short answer is, Yes?goldfish9776 said:as j dot j = 1 , so the product of j and j is only the scalar magnitude, with no unit ?
FBa stands for force in the b-direction and is a vector quantity that represents the magnitude and direction of a force. It is important to solve for FBa in order to accurately calculate the net force acting on an object.
59N is the magnitude of the force in the b-direction, while 50.6j + 8.43k represents the components of the force in the x and y directions respectively. In order to find the total force in the b-direction, these components must be added together, resulting in 59N.
The direction of FBa is determined by the direction of the force vector. In this case, the force is acting in the b-direction which is typically represented by a perpendicular line to the x and y axes.
FBa is typically measured in newtons (N), which is the standard unit for force in the International System of Units (SI).
Yes, FBa can be negative if the force is acting in the opposite direction of the chosen positive direction. In this case, it would indicate that the force is acting in the negative b-direction.
