ohhhhhh! so simply because its a circular motion therefore we equate the two equations...i see...so yeah then the radius decreases implying the deflection is larger! thanks a bunch!
It says that a decrease in potential difference would decrease v and thus cause a larger deflection. Thats all it says. I'm assuming they used F=mv^2/r to come to that conclusion.
1. Okay so thsi comes from Oct/Nov 05 Physics Paper 4. Question 5 b (ii) 1. The diagram shows a magnetic field into the paper and an electron moving in a straight horizontal line about to enter the field. The question asks what effect is there on the deflection of the electron if the potential...
