How much work is required to stop an electron (m=9.11×10−31kg) which is moving with a speed of 1.90×106 m/s ? Express your answer to three significant figures and include the appropriate units.
SOLUTION :
=> Apply work - energy theorem,
=> Work done = change in kinetic energy
=> 0.5* 9.11*10^-31*(0 - (1.9*10^6)^2)
=> - 1.64 * 10^-18 J (In three significant figures)
