Answer questions on resultante of non-linear Activity
forcos
The forces act on an object. The first is a horizontal 50 N force. The
second is a 40 N force acting at an angle to the horizontal
Use a graphical method drawn to a scale of 1mm :1N to find the
resultant at the 40N force is inclined at
1.11 30° to the horizontal
1.1.2 60° to the horizontal​

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

i do.

explanation:

i want to explore the wonders of the universe and find out if there really is life out there. i think the universe is beautiful.
