Answer» since two resistance are parallel 1/Rp= (1/3 +1/6 ) Rp= 2ohm Now other three are in paralllel 1/Rp = 1/3 +1/6+1/2 1/Rp= 6/6ohm=1OHM Rp= 1ohm Now above two are in parallel so Rs (EQ)= 2+1=3ohm total voltage = 12v i = V/R=12/3=4A since the 3 ohm and 6ohm are in paralllel so using current DIVISION rule current in 3ohm is 4/3a and In 6 ohm is 8/3a Now 4/3A is divided in 3 resistor so current divided in ratio 3:2:1 so current in Ammeter is = 4A in downward Now current in Ammeter DUR to 6ohm resistor= 2A upward so reading of Ammeter is = 4 - 2 = 2A upward . |

|
Answer» _______________________________ GIVEN : Potential energy = 100 J g = 10m/s² Height (h) = 20m To find : Mass = ? Solution : We KNOW that, Potential energy = mass × acceleration × height PE = mgh Now put the given values : 100 J = m × 10m/s² × 20m 100 J = m × 200 200m = 100 m = 100/200 m = 1/2 = 0.5 kilogram.
