Acceleration= change in velocity/time=27.8-0/4.8=5.792 ms⁻²
Force= Mass*acceleration=66*5.792=382.25 N
Answer:
The banking angle of the road is 15.8⁰.
Explanation:
Given;
radius of the curved road, r = 52 m
velocity of the traveling car, v = 12 m/s
acceleration due to gravity, g = 9.8 m/s²
let the banking angle of the road = θ
The banking angle of the road is calculated as;
Therefore, the banking angle of the road is 15.8⁰.
Answer:
(a)
(b) The force is repulsive
Explanation:
a) According to Coulomb's law, the magnitude of the electrice force that one particle exerts on the other is defined as:
Here k is the coulomb constant, and are the signed magnitudes of the charges and d is the distance between them.
b) According to Coulomb's law, if the two charges have the same sign, the electrostatic force between them is repulsive.
Answer:
100 N
Explanation:
Given that,
Two forces whose resultant is 100newton are perpendicular to each other.
If one of them makes an angle of 60newton with the resultant.
and
The magnitude of force,
or
F = 100 N
So, the magnitude of force is 100 N.
