A small conducting spherical shell with inner radius a and outer radius \( \mathbf{b} \) is concentric with a larger conducting spherical shell with inner radius \( c \) and outer radius \( d \). The inner shell has a total charge of \( -1 q \) and the outer shell has a total charge of \( +4 \mathbf{q} \) Select True or False for the following statements. The total charge on the outer surface of the small shell is \( -5 q \). The electric field in the region \( cd \) is given by \( +4 q /\left(4 \sqcap \varepsilon_{0} r^{2}\right) \). The total charge on the inner surface of the small shell is \( -1 q \). The electric field in the region \( r
