Which one is not correct for a vector A= 2i+2j+3k ??
View Answer Explanation
A central force is that which ??
The resultant of two forces of equal magnitudes is also equal to the magnitude of the forces. The angle between the two forces is ??
What is the angle that the given vector makes with the y-axis and A=2i+3j ??
Three coplanar forces acting on a body keep it in equilibrium. They should therefore be ??
In which quadrant the two rectangular components of a vector have the same sign ??
Which of the following pairs does not have identical dimensions ??
Two vectors A and B are making angle θ with each other. The scalar projection of vector B on vector A is written as ??
It is easier to turn a steering wheel with both hands than with a single hand because ??
Two vectors are A = 3i^+2j^ -k^& B = 3i^-2j^ +k^ , then ??
The cross product i^ x j^ is equal to ??
