This question is in two parts

The magnitude of gravitational field strength g is defined from the equation shown below.

g=\frac{F_{\mathrm{g}}}{m}

The magnitude of electric field strength E is defined from the equation shown below.

E=\frac{F_{\mathrm{E}}}{q}

For each of these defining equations, state the meaning of the symbols

$F_{\mathrm{E}}$ .
