Question

A particle of mass 0.5gm moving along the x-axis is located at x = 15m at T1=5sec and at X2 - 33m at T2= 13 second its Velocity is​

Answer 1

0.327 weber/meter square

Explanation:

we know force =mass-acceleration due to gravity

=0.5x9.8m/s^2

thus force=4.9N

also we know force =q[vxB]

B=4.9/2.5×6×10×10×10×10

=0.327 weber per meter square
