Answer the Questions by appropriately matching the information given in the three columns of the following table.
A charged particle (electron or proton) is introduced at the origin $$(x = 0, y = 0, z = 0)$$ with a given initial velocity $$\overrightarrow{v}$$. A uniform electric field $$\overrightarrow{E}$$ and a uniform magnetic field $$\overrightarrow{B}$$ exist everywhere. The velocity $$\overrightarrow{v}$$, electric field $$\overrightarrow{E}$$ and magnetic field $$\overrightarrow{B}$$ are given in columns 1, 2 and 3 respectively. The quantities $$E_0, B_0$$ are positive in magnitude.
In which case will the particle describe a helical path with axis along the positive z direction?
