In this paper, motivated by recent works on the study of the equations which model the electrostatic MEMS devices, we study the quasilinear elliptic equation involving a singular nonlinearity According to the choice of the parameters science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0362546X16302231&_mathId=si2.gif&_user=111111111&_pii=S0362546X16302231&_rdoc=1&_issn=0362546X&md5=2a647da511b31f17216ab4b8527a76e5">$\alpha ,\beta$ and science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0362546X16302231&_mathId=si16.gif&_user=111111111&_pii=S0362546X16302231&_rdoc=1&_issn=0362546X&md5=52453dd584fc57c6c0e2e1acdbf4c12f" title="Click to view the MathML source">γ$\gamma$, the differential operator which we are dealing with corresponds to the radial form of the Laplacian, the science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0362546X16302231&_mathId=si4.gif&_user=111111111&_pii=S0362546X16302231&_rdoc=1&_issn=0362546X&md5=c09f5b29c4e6f78c33813412438553dc" title="Click to view the MathML source">p$p$-Laplacian and the science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0362546X16302231&_mathId=si5.gif&_user=111111111&_pii=S0362546X16302231&_rdoc=1&_issn=0362546X&md5=add9ec4d8ea092b2e8f4a43876351d08" title="Click to view the MathML source">k$k$-Hessian.
