Answer
The electric field strength ET at a distance 2R from the surface can be determined using the formula for the electric field outside a charged spherical conductor:
ET=4E
Thus, the electric field strength at point T is rac{E}{2}.

Answer
The electric potential VT at a distance 2R from the surface is calculated using the formula for electric potential:
VT=4V
Hence, the electric potential at point T is rac{V}{4}.
