An electron of mass m (9.1 times 10-31 kg) and charge q (-1.6 times 10-19 c) is accelerated to the right (in the plane of the page) from rest through a potential difference v = 1500 v. the electron then enters a region, defined by x > 0, containing a uniform magnetic field b = 0.3 t directed out of page. how much time, t (in seconds), does the electron spend in the magnetic field region?

The time is

Explanation:

Given that,

Mass of electron

Charge of electron

Potential difference = 1500 V

Magnetic field = 0.3 T

We need to calculate the speed of electron

Using formula of force

We need to calculate the time

Using centripetal force

Put the value into the formula

Hence, The time is

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2
