Figure 30-61 shows a uniform magnetic field `vecB` confined to a cylindrical volume of radius R. The magnitude of `vecB` is decreasing at a constant rate of 10 mT/s. In unit-vector notation, what is the initial acceleration of an electron released at (a) point a (radial distance r = 5.0 cm), (b) point b (r = 0), and (c) point c (r = 5.0 cm)?

Explanation

`(a)(4.4 xx 10^(7) m//s^(2))hati,(b)0, (c)-(4.4xx 10^(7) m//s^(2))hati`
