Which of the following forces can be used to pick up scattered iron pins?
Electrostatic force
Frictional force
Magnetic force
Gravitational force
Iron pins, being magnetic in nature, are attracted towards a magnet. This principle can be used to pick up scattered iron pins.
Which of the following is not a no-contact force ? (a) electrostatic force (b) gravitational force (c) frictional force (d) magnetic force
Which of the following are non-contact forces?
Magnetic force, Frictional force, Gravitational force, Electrostatic force.
