What is the range of gravitational force. ?
The gravitational force of attraction between two bodies of masses 40 kg and 80 kg separated by a distance of 15 m is: (Take Gravitational constant, G=6.673×10−11Nm2kg−2)
Calculate the gravitational force between 2 stars having mass 1025 kg and 5×1030 kg respectively. Distance between them is 2×1010m.
A bullet is fired from a canon with velocity 500 m/s. If the angle of projection is 15∘ and g=10 m/s2. Then the range is
