The force of friction is 399.7 N
Explanation:
The force of friction acting on the bear is given by
(1)
where
is the coefficient of friction
N is the normal reaction exerted by the plane on the bear
The normal reaction can be found by analyzing the forces acting in the direction perpendicular to the plane: in fact, the bear is in equilibrium along this direction, so the normal reaction must balance the component of the weight perpendicular to the plane:
where:
m = 900 kg is the mass of the bear
is the acceleration of gravity
is the angle of the incline
Substituting everything into (1), we find the force of friction:

Answer:
F = 10.788 N
Explanation:
Given that,
Charge 1,
Charge 2,
Distance between charges, d = 0.1 m
We know that there is a force between charges. It is called electrostatic force. It is given by :
So, the force applied between charges is 10.788 N.
