No, you can't say that. 
All you can say is the SUM of Object-A's momentum PLUS Object-B's momentum
is the same before and after the collision.

A circular coil of radius 5.0 cm and resistance 0.20 Ω is placed in a uniform magnetic field perpendicular to the plane of the c
DedPeter [7]

Answer:

The induced current in the coil at the time 2 s is 0.00263 A

Explanation:

The equation for induced emf is equal to:

\epsilon =-\frac{d}{dt} (BAcos\theta )

Where

B = magnetic field

A = area

θ = angle

\epsilon =-Acos0\frac{d}{dt} B\\\epsilon =-(\pi r^{2} )\frac{d}{dt} (0.5e^{-0.2t} )\\\epsilon =0.1 (\pi r^{2} )e^{-0.2t}

For t = 2 s

\epsilon =0.1*\pi *0.05^{2} *e^{-0.2*2} =5.26x10^{-4} V

The induced current is:

I=\frac{\epsilo }{R} =\frac{5.26x10^{-4} }{0.2} =0.00263A
