The direction of vector in space is specified by

• 1- angle A
• 2- angle B
• 3- angle C
• 4 - angle D

The resultant of two forces 3N and 4 N acting at right angle to each other is.

• 5 N A
• 6 N B
• 1 N C
• 7 N D

Usually the x-axis is taken as

• Vertical axis A
• Horizontal axis B
• +ve axis C
• -ve axis D

Head to tail rule is used for

• Addition of vectors A
• Subtraction of vectors B
• Multiplication of vectors C
• Division of vectors D

A direction of torque is

• Along the position vector r A
• Perpendicular to both r and f B
• Along the direction of force F C
• Opposite to the direction of r D

The resultant of two forces 3 N and 4 N acting at right angle to each other is

• 7 N A
• 5 N B
• 4 N C
• 1 N D

A force of 10N makes an angle 30o with y axis. Then magnitude of x -component is.

• 5 N A
• 8.66 N B
• 10 N C
• Zero D

Vectors have

• Numerical value A
• Directional B
• Both a and b C
• None of these D

The sum of two or more vectors will be a single vector called

• Component vector A
• Position vector B
• -ve vector C
• Resultant vector D

If a vector of magnitude 10 N along y-axis then its component along x-axis is

• 0 N A
• 5 N B
• 8.66 N C
• 10 N D

If r = 5 m and f = 4 N are along same direction, them torque is

• 20 Nm A
• 5 Nm B
• 10 Nm C
• Zero D

The angle between x-axis, y-axis and z-axis is

• 45° A
• 60° B
• 75° C
• 90° D

Two vector can be added by simple arithmetical method when they are at an angle of.

• 120^o A
• 90^o B
• 0^o C
• 45^o D

The resultant of two vectors having magnitude 10 N and 8 N Can not be

• 2 N A
• 9 N B
• 18 N C
• 20 N D

Which is the example of vector quantity

• Torque A
• Speed B
• Density C
• Work D

The magnitude of A will be

• Zero A
• A² B
• 1 C
• A D

• Unit vector A
• +ve of a vector B
• Resultant vector C
• -ve of a vector D
