by putting the equation of motion v2-u2=2as u will get 4×10^5m/s2 acceleration and then put the formula F=ma nd get this answer4×10^6N

hey,
your answer is below...

Acceleration = (v^2/2d)
= (200^2/0.1m)
= -400,000m/sec. 
F = (ma)
= 0.01kg*400,000
= 4,000N.

I hope this information is useful for you.
