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
• (C) 5 - 10 kg
• (D) 25 - 30 kg
