Question

The range of projectile is $R$ when the angle of projection is ${55}^{\circ }$. For the same velocity of projection and range, the other possible angle of projection is

• A. ${60}^{\circ }$
• B. ${45}^{\circ }$
• C. ${35}^{\circ }$
• D. $\text{Not possible}$

Answer 1

The correct option is C ${35}^{\circ }$

For the same velocity of projection and range, other possible angle of projection is the complementry angle i.e. ${90}^{\circ }-{55}^{\circ }={35}^{\circ }$.
