A semicircle of radius R = 5m with diameter AD as shown in figure. Two particles 1 and 2 are at points A and B on shown diameter at t = 0 and move along segments AC and BC with constant speeds `u_(1)` and `u_(2)` respectively. Then the value of `(u_(1))/(u_(2))` for both particles to reach point C simultaneously will be : A. `(5sqrt(2))/(4)m//sec`B. `(2sqrt(2))/(5)m//sec`C. `2sqrt(2)m//sec`D. `sqrt((5)/(4)m//sec` |

Answer» Correct Answer - D A semicircle ……………….. From geometry `BC = 4m and AC = 2sqrt(5)m` . `(AC)/(u_(1)) = (BC)/(u_(2)) or (u_(1))/(u_(2)) = (AC)/(BC) = (2sqrt(5))/(4)` |
