These questions consists of two statements each printed as Assertion (A) and Reason (R). While answering these question you are required to choose any one of the following four responses Assertion (A) A particle in X Y-plane is governed by x=a sin ω t and y=a cos ω t where a as well as ω are constants, then the particle will have parabolic motion. Reason (R) A particle under the influence of mutually perpendicular velocities has curvilinear motion.

h1=(u2/2 g), h2=(u2 sin 2 30°/2 g)=(u2/8 g)

Both $A$ and $R$ are true and $R$ is not the correct explanation of A .

A is true but R is false.

$A$ is false but $R$ is true.

Both $A$ and $R$ are true and $R$ is the correct explanation of $A$ .

$h_{1} = \frac{u ^{2}}{2 g}, h_{2} = \frac{u ^{2} s i n ^{2} 3 0 ^{\circ}}{2 g} = \frac{u ^{2}}{8 g}$

Both A and R are true and R is not the correct explanation of A .

A is true but R is false.

A is false but R is true.

Both A and R are true and R is the correct explanation of A.

h1​=2gu2​,h2​=2gu2sin230∘​=8gu2​

Both $A$ and $R$ are true and $R$ is not the correct explanation of A .

$A$ is false but $R$ is true.

Both $A$ and $R$ are true and $R$ is the correct explanation of $A$ .

$h_{1} = \frac{u ^{2}}{2 g}, h_{2} = \frac{u ^{2} s i n ^{2} 3 0 ^{\circ}}{2 g} = \frac{u ^{2}}{8 g}$
