The particle will hit T if projected at an angle 45^\circ from the horizontal

The particle will hit T if projected either at an angle 30^\circ or 60^\circ from the horizontal

Time taken by the particle to hit T could be \sqrt{ \frac{5}{6}} \\mu {s} as well as \sqrt{\frac{5}{2}} \\mu{s}

Time taken by the particle to hit T is \\sqrt{\frac{5}{3}} \\mu{s}

=−400√3

NC−1 is applied in a region. A charged particle of mass mcarrying positive charge q is projected in this region with an initial speed of 2√10×106ms−1. This particle is aimed to hit a target T, which is 5m away from its entry point into the field as shownschematically in the figure. Take

=1010Ckg−1. Then
