A plane is inclined at an angle $\mathrm{\alpha }=30°$ with respect to the horizontal. A particle is projected with a speed $\mathrm{u}=2\mathrm{ }\mathrm{m}\mathrm{ }{\mathrm{s}}^{-1}$ , from the base of the plane, making an angle $\mathrm{\theta }=15°$ with respect to the plane as shown in the figure. The distance from the base, at which the particle hits the plane is close to:
(Take $\mathrm{g}=10\mathrm{ }\mathrm{m}\mathrm{ }{\mathrm{s}}^{-2}$ )

• Correct answer
  A

  $20\mathrm{ }\mathrm{c}\mathrm{m}$
• B

  $18\mathrm{ }\mathrm{c}\mathrm{m}$
• C

  $14\mathrm{ }\mathrm{c}\mathrm{m}$
• D

  $26\mathrm{ }\mathrm{c}\mathrm{m}$

Hence, the correct answer is option: 'A'.
