The resultant of the two vectors

\vec{A}

and

\vec{B}

makes angle

\alpha

with

\vec{A}

and

\beta

with

\vec{B}

.

Statement (A) :

\alpha<\beta

|\vec{A}|<|\vec{B}|

Statement (B) :

\alpha<\boldsymbol{\beta}

|\overrightarrow{{A}}|>|\vec{B}|

Statement (C) :

\alpha=\beta

|\vec{A}|=|\vec{B}|

View answer and explanation

Correct option: C

(B) and (C) are true

Option C is correct because the angle a vector makes with the resultant depends on the magnitudes of the vectors; if |A| > |B|, then α < β, and if |A| = |B|, then α = β.

Given,

\mathrm{\vec P} = \mathrm{\vec A} + \mathrm{\vec B}\,\,\mathrm{and}\,P = A + B.

The angle between

\mathrm{\vec A}\,and\,\mathrm{\vec B}

is Assertion: The necessary condition for motion in two dimensions, velocity and acceleration vectors should have any angle between

0^{\circ}

and

90^{\circ}

between them.
Reason: For two-dimensional or three-dimensional motion, velocity and acceleration of an object works in opposite direction.

\mathrm{If}\,(\mathbf{a}+3 \mathbf{b}) \cdot(7 \mathbf{a}-5 \mathbf{b})=0

and

(\mathbf{a}-4 \mathbf{b}) \cdot(7 \mathbf{a}-2 \mathbf{b})=0

. Then, the angle between

\mathbf{a}

and

\mathbf{b}

is At the top of the trajectory of a projectile, the direction of its velocity and acceleration are A ball is thrown at an angle

\theta

and another ball is thrown at an angle

\left(90^{\circ}-\theta\right)

with the horizontal direction from the same point with velocity

39.2 \mathrm{~ms}^{-1}

. The second ball reaches

50 \mathrm{~m}

higher than the first ball. Find their individual heights. Take

{g}=9.8 \mathrm{~ms}^{-2}

. Assertion: The drover in a vehicle moving with a constant speed on a straight road is in a non-inertial frame of reference.

Reason: A reference frame in which Newton's laws of motion are applicable is non-inertial.
