If are two vectors inclined to each other at an angle θ, then the component of perpendicular to and lying in the plane containing will be:

A

B

C

D

Solution

From the diagram-
Question 2

A

B

C

D
at an angle of 45°

Solution
Question 3
1 / -0

A

B

C
is antiparallel to

D
makes an angle of 120° with

Solution
Question 4
1 / -0

Two forces of the same magnitude are acting on a body in the East and North directions, respectively. If the body remains in equilibrium, then the third force should be applied in the direction of:

A
North-East

B
North-West

C
South-West

D
South-East

Solution

The resultant of these two forces would lie in the north-east direction. To balance this resultant, the third force should be in a south-west direction.

Solution
Question 6
1 / -0

In the following questions, a statement of assertion (A) is followed by a statement of the reason (R).

A: Three vectors equal in magnitude cannot produce zero resultant.

R: Minimum four-vectors required to produce zero resultant.

A
If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).

B
If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).

C
If Assertion is a true statement but Reason is false, then mark (3).

D
If both Assertion and Reason are false statements, then mark (4).

Solution

The resultant of three vectors equal in magnitude can be equal to zero if the angle between them is 120° as shown in the figure.
Question 7
1 / -0

In the following questions, a statement of assertion (A) is followed by a statement of the reason (R).

A: A vector must have, magnitude and direction.

R: A physical quantity cannot be called a vector if its magnitude is zero.

A
If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).

B
If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).

C
If Assertion is a true statement but Reason is false, then mark (3).

D
If both Assertion and Reason are false statements, then mark (4).

Solution

A null vector has zero magnitude and has no or any direction.
