MCQ
Two projectiles $A$ and $B$ are thrown with the same speed but angles are $40^{\circ}$ and $50^{\circ}$ with the horizontal. Then
  • A will fall earlier
  • B
    $B$ will fall earlier
  • C
    both will fall at the same time
  • D
    None of these

Answer

Correct option: A.
A will fall earlier
a
(a)

$T =\frac{2 u \sin \theta}{ g }$, lesser is the value of $\theta$, lesser is $\sin \theta$ and hence lesser will be the time taken. Hence A will fall earlier.

A bob of mass $10$ $M$ is suspended through an inextensible string of length $l$. When the bob is at rest at the equilibrium position, two particles of mass $m$ each moving with velocity $u$ making an angle $60^o $ with the string strike and get simultaneously attached to the bob. What is the value of impulsive tension $(l)$ in the string during the impact ?
