Two rings of radius 5 cm are 20 cm apart and concentric with a common horizontal x-axis. the ring on the left carries a uniformly distributed charge of +30 nc, and the ring on the right carries a uniformly distributed charge of −30 nc. what is the electric field due to the right ring at a location midway between the two rings?

The electric field due to the right ring at a location midway between the two rings is

Explanation:

Given that,

Radius of first ring = 5 cm

Radius of second ring = 20 cm

Charge on the left of the ring = +30 nC

Charge on the right of the ring = -30 nC

We need to calculate the electric field due to the right ring at a location midway between the two rings

Using formula of  electric field

Put the value into the formula

Hence, The electric field due to the right ring at a location midway between the two rings is

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
