SCALAR AND VECTOR QUANTITY

PHYSICAL QUANTITIES HAVING ONLY MAGNITUDE BUT NO DIRECTION ARE CALLED

• SCALAR QUANTITIES

• VECTOR QUANTIES

• PHYSICAL QUANTITIES

• BOTH 1 AND 2

VECTORS CANNOT BE ADDED , SUBSTRACTED , MULTIPLIED BY ORDINARY LAWS OF -----------------

• GEOMETRY

• ALGEBRA

• BOTH 1 AND 2

• NONE OF THESE

MAGNITUDE OF A VECTOR CANNOT BE ---------

• POSITIVE

• NEGATIVE

• ZERO

• UNIT

WHAT IS AN ANGLE OF TWO VECTORS OF ORTHOGONAL VECTOR

• 45*

• 60*

• 90*

• 180*

DIRECTION OF NULL VECTOR

• CAN BE DETERMINED

• CANNOT BE DETERMINED

• ZERO

• ALL OF ABOVE

A VECTOR CANNOT BE CHANGED IF

• IT IS ROTATED THROUGH AN ARBITARY ANGLE

• IT IS MULTIPLIED THROUGH AN ARBITARY SCALAR

• IT IS ROTATED THROUGH AN ARBITARY AXIS

• NONE OF ABOVE

WHICH OF A FOLLOWING IS A SCALAR QUANTITIES ( MULTI CORRECT )
