Từ điểm O trên mặt đất một chất điểm được ném lên với vận tốc ban đầu vO = 10 m/s hợp với phương ngang một góc α = 30 0. Tìm bán kính cong tại điểm cao nhất của quỹ đạo (tính ra mét)? Lấy g =
10 m/m 2.

What will a positive and a negative charge do if they are separated from each other?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
