The component of a vector ( r ) along ( x ) - axis will have a maximum value if
Options
- A( r ) is along ( + ) ve ( x )-axis
- B( r ) is along ( + ) ve ( y- ) axis
- C( r ) is along - ve ( y ) - axis
- D( r ) makes an angle of ( 45^ ) with the ( x )-axis
Correct answer
A. ( r ) is along ( + ) ve ( x )-axis
Step-by-step solution
The component of a vector ( r ) along ( x )-axis is given as ( r ). If ( =0^ , ) will have maximum value, that is, ( +1 ). Thus, component of a vector ( r ) along ( x ) axis will have a maximum value if ( r ) is along positive ( x )-axis.
