Speed of the arrow just before it will hit the ground can be calculated by energy conservation
by solving above equation
now this will lodge itself 15 cm into the ground
so after lodging itself to 15 cm the speed of arrow becomes zero
now we will have
Now by Newton's II law net force is given as
The value of Q will be -8 C.
In the presence of an electric or magnetic field, matter experiences a force due to its electric charge.
A moving electric charge generates a magnetic field, and an electric charge has an accompanying electric field.
The information provided in the issue is;
The separation between and is 2m.
The separation between and is 2m.
An origin charge equals +2 C
The electric fields are identical in magnitude but are facing in different directions. As a result, the following relationship can be used
Q/16=1/2
The value of Q will be -8 C.

As per the kinematics equation
when glove comes back to his hand the displacement will become zero
Part b)
Now as per symmetric nature the time to reach the top will be same as the time to come back again
so here we can say
so it took 0.61 s to reach the top
The answer is d.acid rain and air pollution
The correct answer is direct.
