The magnitude of the electric field just outside the surface of the sphere is
given:
radius,r=0.01m
charge,Q=1.0×10-9
what is electric field?
Electric field is defined as the electric force per unit charge.It is surrounded by electrically charged particles and exerts force on all other charge particles.
using formula,
for just outside r=radius of sphere
Thus,the electric field just outside the surface of the sphere is

Answer:
No external contact force.
Explanation:
Mass is defined as the amount of material an object contains, that doesn't change whether the object it on earth, on the moon or anywhere in space. Except the only force that is acting upon the body in gravity and they don't feel gravitational attraction towards the earth.
Answer:
Angular acceleration is defined as the rate of change of angular velocity of a body.
consider the attached figure as shown
It rotates with an angular velocity
An point inside the object rotates along the path as indicated thus turning by an angle in time 't'
Thus we have
physically angular acceleration can be understood as the rate at which the angular speed of any object is changing with time.
