A glass full of water is placed on a weighing scale, which reds 10 N, A coin with weight 1 N is gently released into the water. At finrst the coin accelerates as it falls and about halfway down the glass, the coin reaches terminal velocity eventually the coin rests on te bottom of the glass, accelerationdue to gravity is `10m//s^(2)`. The scale roads (a). 10.5N when the coin accelerates at `5m//s^(2))` (b). 11.5 N when the coin decelerates at `5m//s^(2)` (c). 11N, when the coin moves with terminal velocity (d). 11N when the coin rests on the bottom. |

Answer» Correct Answer - A::C::D When coin moves with terminal velocity or rests on the bottom Reading `=10+1=11N` When coin moves with acceleration of `5m//s^(2)` Reading `=10+1(1//2)=10.5N` |
