Is the inverse of the angular momentum C. the inverse of the torque Is the inverse of the bulk modulus It is the square of the torque It is the inverse of the inertia momentum d. e. 92. The law of gravitation states that: and A. Two objects of mass m and M attract each other with a force proportional to their mass inversely proportional with the distance between them. B. Two objects of mass m and M attract each other with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. C. Two objects of mass m and M attract each other with a force proportional to the product of their masses and inversely proportional to the square of the distance between their center of D. Two objects of mass m and M attract each other with a force proportional to their mass and with the distance between them. E. Two objects of mass m and M attract each other with a force proportional to their mass and inversely proportional with the distance between them. 93. The gravitational force: a. Is a vector b. Lies along the axis that connects the centers of gravity of the two objects c. Is always attractive d. All of the above 94. The unit for the force of gravitational attraction is: a. Joule b. Cavendish c. Newton d. kgm/s e. None of the above 95. The unit for the Young modulus is a. Newton/m2 (N/m2) b.Pascal (Pa) c. kg/(ms2) d. all of the aboveExplanation / Answer
91 The compressibility of solid is inverse of bulk modulus
92 : The law of gravitation was proposed by newton. It states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Option C is the correct alternative
93. As per the above definition in 92 all of the abouve is correct
94 Unit of force is netwon. So naturally unit of gravitational force is also newton
95 Unit of young's modulus is newton/m2 or pascal or kg/ms2 Hence all of the above is correct
