Properties of Vector Addition, Resolution and Composition

1. The sum of two or more vectors is a single vector which is called:

• A. A resultant vector

• A. A negative vector

• A. A position vector

• A. A null vector

Geometrical method of addition of vector is:

• Head to tail rule method

• Rectangular components method

• Right hand method

• Hit and trail method

1. A + B = B + A This law is called:

• Associative law of vector addition

• Commutative law of vector addition

• Distributive law of vector addition

• Affirmative law of vector addition

(A + B) + C = A + (B + C) this law is called:

• Associative law of vector addition

• Commutative law of vector addition

• Distributive law of vector addition

• Affirmative law of vector addition

The components of vector which are perpendicular to each other are called:

• Triangular components

• Rectangular components

• Equal components

• Similar components

The vector A makes an angel with x – axis then its X – components is given by:

• A Sin theta
  

• A Cos A theetha

• theta Cos A

• theta Sin A

1. The vector A makes an angel with y – axis then its Y – components is given by:

• A Sin theta

• A Cos theta

• theta Cos A

• theta Sin A

Two forces of 10 N and 15 N are acting simultaneously on an object in the same direction, their resultant is:

• 0 N

• 5 N

• 25 N

• 150 N

Two equal forces F and F makes an angle of 180 degrees with each other, the magnitude of their resultant is:

• 0

• F

• 2F

• 3F

The resultant of two force of magnitude 5 N and 10 N cannot be:

• 4 N

• 6 N

• 9 N

• 13 N
