in a region uniform electric field E=10^3 N/C exists along +y axis .a charged particle (mass =1g, charge =1mC) enters with velocity 10 m/s along +x axis find speed of the particle when displacement along x axis is 10 cm.

Question

Shailendra Kumar Sharma · Answer

Assume the particle is moving along X-axis and Along +Y Axis there is an Electric field. It can be assumed a gravitational field.
so the force on object will be qE and acceleration along +Y axis will be qE/m

a=qE/m

a= {1x10^-3 * (10³)}/(10^-3) =10³ m/s
Now velocity when displacement along x-axis 10cm.
time taken in 10 cm travel will be 10cm/10m/s = 0.01s.
So the y component of velocity will be V_y=at =1000*(.01) =10m/s
So the velocity of particle will be $\sqrt{100+100} =10\sqrt{2}$ or 14.14 m/s
