A positively charged particle moving to the right in the plane of the the paper

Question

A positively charged particle moving to the right in the plane of the the paper with a velocity enters a region with a uniform magnetic field into the page and a uniform electric field into the page and a uniform electric field downward in the plane of the paper. What is the direction of the net force on the particle due to the fields at the instant it enters the fields? Upward(uparrow). Downward (downarrow) Into the page (Theta) No net force. Not enough information to determine the direction of the net force. The figure and v below show the circular points of two different charged particles that travel at the same speed in the same uniform magnetic field directed into the page. One particle is a proton and the other is an electron (which has a smaller mass than a proton). The circle with the smaller radius in figure 1 is traveled by: the proton in a clockwise direction. the electron in a clockwise direction. The proton in a counterclockwise direction. The elect
