1 and 4 are tire.
2 and 3 are not.
The magnitude of the electric current is directly proportional to the "Electric Charge" <span>of the electric field.

It will move to the right and most likely a tiny bit down
All of the above but normally in a triple beam
Explanation:
It is given that,
Weight of the rock in air, W = 110 N
Since, W = mg


m = 11.22 kg
We need to find the apparent weight of the rock when it is submerged in water. Apparent weight is equal to the weight of liquid displaced i.e.

d is the density of water, 
V is the volume of rock, 

M = 3.37 kg
The apparent weight in water, W = m - M

W = 76.93 N
So, the apparent weight of the rock is 76.93 N. Hence, this is the required solution.
