An object traveling a circular path of radius 5 m at constant speed experiences an acceleration of 3 m/s2. if the radius of its path
is increased to 10 m, but its speed remains the same, what is its acceleration?
0.3 m/s2
1.5 m/s2
6 m/s
12 m/s2

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
