There are two incline planes AO and OB inclined at 45° and 60° respectively with the horizontal as shown in the figure. When a man moves on the incline plane AO with speed 10 m/s, he observes that the rain drops are falling 45° with the vertical. When the man moves on the inclined plane OB with speed 20 m/s, he observes that the raindrops are falling vertically downward. Then actual speed of rain is
