Horizontal range of a projectile from a horizontal plane is given by, R=gu2sin2θ.
Clearly for maximum range, sin2θ=1.
Therefore, θ=45∘.
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: When a body is projected at an…

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: When a body is projected at an angle 45∘, its range is maximum.
Reason R: For maximum range, the value of sin 2θ should be equal to one.
In the light of the above statements, choose the correct answer from the options given below:

When a part of a straight capillary tube is placed vertically in a liquid, the liquid raises upto certain height $h$. If the inner radius of the capillary tube, density of the liquid and surface tension of the liquid decrease by $1 \%$ each, then the height of the liquid in the tube will change by $\%$.
