Answer:
correct option is d) 7.0 x 10^-7 N
Explanation:
given data
distance = 175 picometers = 1.75 × m
to find out
electrical force
solution
we know atomic no of uranium is 92
and charge on electron is = 1.6 × C
and electrical force is express as
electrical force = .............1
put here value we get
electrical force =
electrical force = 6.921 × N
so correct option is d) 7.0 x 10^-7 N
Answer:u=42.29 m/s
Explanation:
Given
Horizontal distance=167 m
launch angle
Let u be the initial speed of ball
Range
Answer:
Woke done, W = 4156.92 Joules
Explanation:
The work done by the force can be calculated as :
is the angle between force and the displacement
It is assumed to find the work done for the given parameters i.e.
Force, F = 30 N
Distance travelled, s = 160 m
Angle between force and displacement,
Work done is given by :
W = 4156.92 Joules
So, the work done by the object is 4156.92 Joules. Hence, this is the required solution.
