A jet of water of cross-sectional area 20 sq. cm impinges on a plate at an angle of 60o with a velocity of 10 m/sec. Neglecting the friction between the jet and plate (density of water 1000/9.81 kgm-1 sec2 per cubic meter), the force exerted by the jet on the plate would be in the range

Q. A jet of water of cross-sectional area 20 sq. cm impinges on a plate at an angle of 60^o with a velocity of 10 m/sec. Neglecting the friction between the jet and plate (density of water 1000/9.81 kgm^-1 sec² per cubic meter), the force exerted by the jet on the plate would be in the range

(A) 15 - 20 kg

(B) 20 - 25 kg
