Answer:
Part a)
Part b)
Explanation:
As we know that electric force on electric charge is given as
here we have
E = 153 N/C
now force is given as
Gravitational force on electric charge near surface of earth is given as
now the ratio of two forces is given as
Part b)
Now the ball is balanced by the electric force and the force of gravity on it
so here we have
here we have
Angular acceleration is simply the ratio of the Torque
over the rotation inertia, that is:
Angular acceleration = Torque / Rotational inertia
So substituting the values:
Angular acceleration = 2.4 N m / 4.0 kg m2
<span>Angular acceleration = 0.7 rad/s^2</span>
Protons and Neutrons account for most of an atoms mass
Answer:
Resultant force, R = 10 N
Explanation:
It is given that,
Force acting along +x direction, 
Force acting along +y direction, 
Both the forces are acting on a point object located at the origin. Let the resultant force of the object is given by R. So,
Here 
R = 10 N
So, the resultant force on the object is 10 N. Hence, this is the required solution.
