Q. Liquid nitrogen boils at 77.00 K. Would this experiment needs to be altered if we used water, which boils at 373 K? Why?

Q. An 8 {rm kg} point mass and a 15-{rm kg} point mass are held in place 50.0 {rm cm} apart. A particle of mass m is released from a point between the two masses 20.0 {rm cm} from the 8.00 {rm kg} mass along the line connecting the two fixed masses. Find the magnitude and direction of the acceleration of the particle.
