A small conducting spherical shell with inner radius a and outer radius 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 \( +3 q \). Select True or False for the following statements. The radial component of the electric field in the region \( r \leqslant a \) is glven by \( -1 q /\left(4 n e r^{2}\right) \). The radial component of the electric field in the region \( cd \) is zero. The total charge on the outer surface of the large shell is \( +2 \mathrm{q} \). The total charge on the inner surface of the large shell is \( -4 \mathrm{q} \). Thes \( 0 / 12 \)
