Question

19 2. A body of mass 10 kg is accelerated uniformly from a velocity of 10 m/s. to 20 m/s. in 10 sec. The force acting on the body is 1) 10 N 2) 20 N 3) 30 N 4) 110N​

Answer 1

Answer is 10N, according to Newton’s second law of motion F=ma. And the acceleration is 1 m\s^2. a =v-u/t similarly 20-10/10 =1 m/s^2
