A 9Be nucleus containing four protons and five neutrons has a mass of 1.50×10 26

Question

A 9Be nucleus containing four protons and five neutrons has a mass of 1.50×1026 kg and is traveling vertically upward at 1.80 km/s .

If this particle suddenly enters a horizontal magnetic field of 1.30 T pointing from west to east, find the direction of its acceleration vector the instant after it enters the field.

northward

eastward

westward

southward

If this particle suddenly enters a horizontal magnetic field of 1.30 T pointing from west to east, find the magnitude of its acceleration vector the instant after it enters the field.

a= m/s2

Explanation / Answer

A) The direction is Northward

B) F = q*v*B so a = q*v*B/m

= 4*1.60x10^-19*1800m/s*1.30/1.50x10^-26 = 9.984x10^10m/s^2 ============answer)
