Answer:The mass of an object is 52 kg.
Explanation:
Gravitational force on the object ,F=510 N
Acceleration due to gravity = g =
Mass of the object = m
Force = mass × acceleration
The mass of an object is 52 kg.
Answer:
Explanation:
Radius of the pollen is given as
Volume of the pollen is given as
mass of the pollen is given as
so weight of the pollen is given as
Now electric force on the pollen is given
now ratio of electric force and weight is given as
Maybe the picture helps. The blue block represents the cart with a mass of 3 kg. The person(black block) is pulling the cart to the right with a force F so that the acceleration a is 2 m/s². According to Newton's 2nd law: F = m*a.
