A rod of mass 4m and length L is hinged at the mid point. A ball of mass 'm' moving with speed V in the plane of rod, strikes at the end at an angle of 45^@ and sticks to it. The angular velocity of system after collision is-

A car can cover a distance of 420 km in 7 hours. How much speed should be increased to cover this distance in 6 hours ? कोई कार 7 h में 420 km की दूरी तय कर सकती है | दूरी को 6 h में तय करने के लिए गति कितनी बढ़ानी होगी?

A conducting rod PQ of length L = 1.0 m is moving with a uniform speed v = 2.0 m s^(-1) in a uniform magnetic field B = 4.0 T directed into the plane of the paper. A capacitor of capacity C = 10muF is connected as shown in , then

A boat moves downstream at the rate of 1 km in 7 1/2 minutes and upstream at the rate of 5km an hour. What is the speed (in km/hour) of the boat in the still water? एक नौका 7 1/2 मिनट में 1 किमी की गति से निचल प्रवाह में जाती है और 1 घंटे में 5 किमी को ग॒ति से ऊपरी प्रवाह में जाती है। स्थिर जल में नौका की गति (किमी/घंटा में) कितनी होगी?
