A particle is moving with constant velocity `(6hati+8hatj)m//s`. It corosses x-axis at point `(2,0)`. The rate of separation from origin at this moment is :A. `6ms^(-1)`B. `8ms^(-1)`C. `10ms^(-1)`D. `7ms^(-1)` |

Answer» Correct Answer - A A particle is ………… Rate of seperation at any instant is determined by the component of velocity which is along the line joining the two refrence points. Here x-axis is the line of seperation and hance, rate of seperation `= v_(x) = 6 m//s`. |
