Answer:
F = +17.48 N
Explanation:
We have,
Electric charge is +0.638 C and the electric field is 27.4 N/C to the right.
It is required to find the electric force felt by the electric charge.
When a charged particle is placed in electric field, it will posses electric force. The sign of force depends on the charged particle.
The electric force is given by :
So, the electric force is 17.48 N and the force is positive.
Answer
given,
largest diameter of balls = 9.52 mm = 0.00476 m
radius = 0.00476
smallest diameter of ball = 2.38 mm = 0.00238 m
radius = 0.00119
viscosity = 1.5 Pa.s
density of the ball = 1.42 g/cm
for small balls
t = 0.033 ms
for larger ball
t = 0.531 ms
The answer is it's middle the nueculs
