Web71. A solid metallic sphere has a charge +3 Q. Concentric with this sphere is a conducting spherical shell having charge – Q. The radius of the sphere is a and that of the spherical shell is b ( b > a ). What is the electric field at a distance R ( a < R < b) from the centre. (1) Q 2πε0R. (2) 3Q 2πε0R. (3) 3Q 4πε0R2. WebThe neurotransmitters travel through the synaptic cleft and bind to ligand-gated ion channels on the postsynaptic neuron membrane. The channels open and allow chemicals to enter the cell (i.e. sodium). Then positively charged sodium enters the cell and causes the cell to … WebNerve Impulse Transmission Within a Neuron.
