Explanation:
The charge on the electron is, 
The electric field at a distance r from the electron is :
Where
k is the electrostatic constant, 
We know that the electric field lines starts from positive charge and ends at the negative charge. Also, for a positive charge the field lines are outwards while for a negative charge the field lines are inwards.
So, the correct option is " the electric field is directed toward the electron and has a magnitude of 
. Hence, this is the required solution.
Answer:
10989.55932 rad/s
Explanation:
m = Mass of object
M = Mass of neutron star = 
R = Radius of neutron star = 13000 m
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Angular speed
Here, the gravitational force will balance the centripetal force
The greatest possible angular speed an object can have is 10989.55932 rad/s
C :) cause a direction has nothing do do with velocity !
The graph is one single line and, as a system solution refers to an intersection point (in other words, a point in common), we affirm both equations share all of their points and thus, such system has infinite solutions.
