We know that the mass of the log before burning is 5 kg. After it is burnt, the mass of the ash comes out to be 1 kg. So there is a definite mismatch of 4 kg. When the log is burnt, there is the formation of smoke. The air and water present in the wood vaporises to reduce the weight significantly. The combustion actually leads to the formation of carbon dioxide that mixes with the air and also water. The extra mass thus goes into the formation of carbon dioxide and water.

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.
