The electric field generated by a proton is a radial field, so we would see the field lines going radially from the proton toward every direction. I've attached a picture representing the electric field generated by a positive charge, such as a proton, and we can see the field lines going radially from the charge toward every direction.
Answer:
Speration between the slits 
Explanation:
Given that,
Wavelength of light, 
It is incident on a double slit produces a second-order maximum at an angle of 25 degree.
The condition for maxima is given as :
d = seperation between the slits
m = order, m = 2
d = 0.00000289
or
So, the seperation between the silts is 
. Hence, this is the required solution.
If the object is moving at a constant speed, acceleration is 0. So:
The resultant force is 0. So the force pushing the object must be equal to the friction force acting, so
Friction =
90 N
Answer:
A
Explanation:
Ans- A, causes sediments in aquifers that are emptied to compact and the ground above it to sink.
This is one of the major problems for California nowadays. Due to excessive groundwater pumping to satisfy the demand of huge population the aquifers are drying, hence compacting and for that the land above sinks.
The first one is C. Hope this helps!! If you need anymore help just message me and I will try to get back to you quickly and help in any way i can!
