In this paper, we first introduce Riesner-Nordstrom AdS (RN-AdS) black hole in presence of quintessence and cloud of strings. And then we use the Restrict Phase Space (RPS) formulism in the corresponding black holes at the critical point with equation state ωq = −1 3 ,−2 3 ,−1. We take advantage from central charge and Newton’s constant with form of variable and prove the compatibility between weak gravity conjecture (WGC) and weak cosmic censorship conjecture (WCCC). Here, we show that when we use usual RN-AdS black hole with Q M > √G condition, we have weak gravity conjecture. But, in that case the WCCC is violated by WGC conjecture. In order to avoid such violation, we consider the Riesner-Nordstrom AdS (RN-AdS) black hole in the presence of quintessence, quintessence and cloud strings. Here, also one can say that, by using the special central charge, chemical potential, appropriate quintessence, cloud strings parameters and the effective Newton’s constant with suitable conditions one can arrive the compatibility between weak gravity conjecture and weak cosmic censorship conjecture.
