Question 958: Electrostats & Capacitance

Question

A bullet of mass 2 g is having a charge of 2 $$\mu $$C. Through what potential difference must it be accelerated, starting from rst, to acquire a speed of 10 m/s ?

Accepted Answer

Using $${1 \over 2}m{v^2} = qV$$
$$V = {1 \over 2} 	imes {{2 	imes {{10}^{ - 3}} 	imes 10 	imes 10} \over {2 	imes {{10}^{ - 6}}}} = 50\,kV$$

Answer

5 kV

Answer

50 kV

Answer
