Answer:
The magnitude of Force is 8.58×10⁵N and direction is upwards
Explanation:
The work beam does on the pile driver is given by
W=(FCos180°)Δx= -F(0.088m)
From work energy theorem
Choosing y=0 at the the level where the driver first contacts the beam and vi=0 at yi=+3.40m and comes to rest again vf=0 at yf= -0.088m
So
The magnitude of Force is 8.58×10⁵N and direction is upwards
Answer:
Β. 16 με
Explanation:
Data provided in the question
Number of electrons removed = 10^14
And, the charge on one electron =
Based on the above information, the charged on the sphere is
Therefore when we remove the electrons
So, the equation would be
=
Therefore the same amount of the positive charged would be developed
Hence, the correct option is B.
