# Two equal resistances when connected in series to a battery, consume electric power of 60 W. If these resistances are now connected in parallel combination to the same battery, the electric power consumed will be : (a) 60 W (b) 240 W (c) 30 W (d) 120 W

## Question ID - 50314 :- Two equal resistances when connected in series to a battery, consume electric power of 60 W. If these resistances are now connected in parallel combination to the same battery, the electric power consumed will be : (a) 60 W (b) 240 W (c) 30 W (d) 120 W

In series condition, equivalent resistance is 2R

Thus power consumed is 60W= In parallel condition, equivalent resistance is R/ 2 thus new power is

P’= Or P’= 4p = 240 W

 An object is at a distance of 20m from a convex lens of focal length 0.3 m. The lens forms an image of the object. If the object moves away from the lens at a speed of 5 m/s, the speed and direction of the image will be : (a) 0.92×10−3 m/s away from the lens (b) 2.26×10−3 m/s away from the lens (c) 1.16×10−3 m/s towards the lens (d) 3.22×10−3 m/s towards the lens
