Question

tell me fast with explanation to be brainliest

Answer 1

Here the acceleration of the object will be same as they will move together thus it will be

10/7 = acceleration

Now the force acts on the 2kg mass is due to the contact force and hence it will be

10*2/7 = 20/7 .. approximately 3 N

Answer 2

HERE IS UR ANSWER THE CONTACT FORCE IS EQUAL TO 10 NEWTON AS WE NO THAT THE CONTACT FORCE IS FORCE WHICH IS FORCE WHICH MADE DURING CONTACT OF ANY TWO OBJECT .

HERE THE ONE OBJECT HAS 10 NEWTON AND OTHER HAS O NEWTON THEREFORE THE CONTACT FORCE = 10N
