| Abstract: | A static, asymptotically flat, spherically symmetric solutions is investigated in f(R) theories of gravity for a charged black hole. We have studied the weak field limit of f(R) gravity for the some f(R) model such as f(R)=R+ε
h(R). In particular, we consider the case lim
R→0
h(R)/h′(R)→0 and find the space time metric for
f(R)=R+(m4)/(R)]f(R)=R+{\mu^{4}\over R}
and f(R)=R
1+ε
theories of gravity far away a charged mass point. |
