As we know, there is an equation for gravitational force
$$F = \frac{Gm_1m_2}{R^2}$$
While for electromagnetism, it is $$F = q(E + v × B)$$ So is there any true formula to find the weak and strong force?

Yes. In modern physics, one formulates the forces in terms of energy rather than force, as a scalar theory seems to have many advantages over a vector theory.
In 1935, quantum physicist Hideki Yukawa showed that the nuclear potential is of the form,
$$V_{\text{Yukawa}} \left( r \right) = -\frac{g^2}{r} e^ {- \mu r} $$
Where $r$ is radial distance from the interacting particle, $g$ is a scaling constant and $\mu = \alpha m$ is the particle's Yukawa mass ($\alpha$ is another scaling constant).
Coming to the weak nuclear interaction - it is, as the word suggests, better described as an 'interaction' than as a 'force'. There are various kinds of weak nuclear interactions, and finding a general structure in them requires rigorous knowledge of the electroweak theory (which unifies the weak nuclear interaction and quantum electrodynamics).
