Answer:
F = 37.5 N
Explanation:
It is given that,
Mass of the object is 5 kg
Acceleration of the object is 7.5 m/s²
We need to find the force experienced by the object. The force is given by the product of mass and acceleration of an object. So,
F = m
So, the force acting on the object is 37.5 N.
Answer:
The smaller sphere has higher value of electric field than the threshold value of electric field.
Solution:
As per the question:
The radius of the first metal sphere, R = 0.1 m
The radius of the first metal sphere, R' = 0.01 m
Charge on the sphere, Q =
The value of the critical electric field,
Now,
The electric field on the surface of a sphere is given by:
where
K = Electrostatic constant =
Now, for the first metal sphere:
Now, for the second metal sphere:
The Electric field for second metal sphere,i.e., smaller sphere is higher than the threshold or critical value for the Electric field thus smaller sphere discharges quickly as above critical field breakdown occurs.
