Question

4. Two objects repel each other
repulsion could be due to
frictional force only
electrostatic force only
magnetic force only
ОО
either a magnetic or an electro
force​

Answer 1

Explanation:

Frictional force is applied along the surfaces and depends on contact. hence it is not a repulsive force.

Electrostatic and magnetic forces can be either attractive or repulsive. Here, when two objects are experiencing repulsive force because there may be an electrostatic force or a magnetic force.

Answer 2

${\fbox{\fbox{\fbox{\fbox{\huge\pink{1.Question}}}}}}$

Two objects repel each other. This repulsion could be due to

a) frictional force only

b) electrostatic force only

c) magnetic force only

d) either a magnetic or an electrostatic force

${\fbox{\fbox{\fbox{\fbox{\huge\purple{Answer}}}}}}$

Frictional force is applied along the surfaces and depends on contact. hence it is not a repulsive force.

Electrostatic and magnetic forces can be either attractive or repulsive. Here, when two objects are experiencing repulsive force because there may be an electrostatic force or a magnetic force.

∴ The answer is option D.
